Monsoon likely to arrive in delhi within two days with rain forecast and air quality improving
New Delhi: The monsoon is likely to reach Delhi within the next two days, with India Meteorological Department forecasting light to moderate rain and improved weather conditions. The department has issued a yellow alert for the national capital and surrounding areas till Tuesday, warning of rain accompanied by thunderstorms and gusty winds of up to 50 kmph. According to IMD, heavy rain is expected over large parts of north and northwest India over the next three days as the southwest monsoon advances further into the region, supported by favourable moisture conditions. The monsoon is likely to arrive in Delhi by June 24. IMD has predicted a normal monsoon for the season. "Southwest monsoon has further advanced over most parts of Himachal Pradesh, the entire Ladakh and Kashmir region, most parts of Jammu, and parts of Punjab," said RK Jenamani, senior weather scientist at IMD. "The Northern Limit of Monsoon currently passes through Jaipur, Agra, Rampur, Dehradun, Shimla, Pathankot and Jammu. Conditions remain favourable for its advancement over the remaining parts of the North Arabian Sea, more areas of Rajasthan, Punjab, Haryana, Chandigarh, Delhi, western Uttar Pradesh and Himachal Pradesh during the next two days. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Free P2,000 GCash eGift UnionBank Credit Card Apply Now Undo " Despite the forecast of rain from Sunday onward, no significant weather activity was recorded in the capital till late evening. However, the city's air quality continued to improve. Sunday marked the fifth consecutive day of satisfactory air quality, with the Air Quality Index (AQI) standing at 92 (on a 0–500 scale) at 4 pm. The improvement was aided by sporadic rain and surface winds, which helped disperse pollutants. Delhi govt, in a statement, said Punjabi Bagh recorded the lowest AQI among all major city locations, logging a reading of just 62. Officials attributed the cleaner air to consistent enforcement action and on-ground pollution control measures. "In the past 24 hours, 211 old or end-of-life vehicles — petrol vehicles older than 15 years and diesel vehicles older than 10 years — were impounded," the statement said. "Additionally, 11,157 pollution challans were issued across the city." Environment minister Manjinder Singh Sirsa said, "Our strict action on old vehicles and field-level monitoring is producing measurable results. From citywide improvements to local successes like Punjabi Bagh, Delhi is steadily moving towards a cleaner air reality." On the weather front, Delhi experienced a partly cloudy sky on Sunday, with a slight drop in daytime temperatures. The Safdarjung base station recorded a maximum temperature of 36.2°C, two degrees below the normal for this time of year, compared to 37.3°C a day earlier. The minimum temperature stood at 28.4°C, marginally higher than Saturday's 27.8°C but still within the seasonal average. Despite the slight dip in temperature, high humidity pushed the discomfort levels up. The heat index, or 'feels-like' temperature, touched 47.5°C. However, IMD expects the maximum temperature to ease further over the coming days, hovering between 33°C and 35°C on Monday, with a possibility of light showers by evening. MSID:: 122007851 413 |

Storm warning: Delhi's thunderstorms left 75 flights diverted in May
Delhi airport faces flight disruptions due to pre-monsoon thunderstorms. May saw numerous diversions and delays. One day witnessed 49 flight diversions. Thunderstorms pose challenges during takeoff and landing. Wind shifts and squalls contribute to safety concerns. Historically, Delhi experiences many thunderstorms annually. Weather is a significant factor in aviation incidents. Recent disruptions surpass previous records. Tired of too many ads? Remove Ads Tired of too many ads? Remove Ads As Delhi transitions into peak pre-monsoon season, the skies over IGI Airport have turned increasingly turbulent—literally. May alone witnessed six major thunderstorms disrupting flight schedules, causing over 75 diversions and hundreds of delays, Times of India has of the most significant incidents occurred on May 25, when 49 flights were diverted due to stormy weather, making it one of the worst days for air travel this thunderstorms typically last only a few minutes, their impact ripples through the aviation network for hours.'Of all the weather-related hazards, thunderstorms have the highest impact on aviation across the world,' TOI quoted R K Jenamani, senior scientist at the India Meteorological Department (IMD), as saying. These storms, often accompanied by lightning, gusty winds, squalls, and even hail, pose serious challenges during takeoff, cruising, and landing phases of wind direction shifts during storms prevent safe takeoffs and landings. On May 2, an intense storm with a squall reaching 74 kmph forced the diversion of three flights and delayed over 500 others. A similar squall on May 17 led to six "go-arounds", a safety maneuver where pilots abort landing attempts and circle back, while more than 300 flights experienced Delhi averages 45 thunderstorms annually, with around 29 occurring between May and August. A study titled 'Characteristics of Thunderstorms and Squalls over IGI Airport', as reported by TOI, analyzing data from 1995–2005, noted the highest thunderstorm activity in June, followed by July, with squalls most frequent in May and June.'More than 80% of thunderstorms in each season are of duration less than three hours,' the study found, with peak pre-monsoon activity typically occurring between 12:00 and 15:00 turbulence during storms is often caused by unstable air currents- strong updrafts that can lift aircraft suddenly, followed by downdrafts that may cause them to drop altitude rapidly. These conditions not only disrupt schedules but also pose safety remains a significant factor in aviation incidents globally. A study titled 'Bad Weather and Aircraft Accidents – Global Vis-à-vis Indian Scenario' revealed that 21% of aircraft accidents in India between 1992 and 2008 were weather-related, compared to 26–32% worldwide. In both India and the US, wind-related issues accounted for the highest share of these May 2018, about 70 Delhi-bound flights were diverted due to storms—then considered one of the worst impacts in recent memory. Last month's figures now surpass that, marking a sharp reminder of the growing challenge weather poses to aviation.(With inputs from TOI)

Flightmare! Storms Wreaking Havoc On Airport Schedules
New Delhi: Last month, over 75 flights were diverted when thunderstorms with speeds of 50-80 kmph hit Delhi airport . While thunderstorms pass in a few minutes, they cause a cascading effect, leading to flight delays throughout the day. Around IGI airport, 45 thunderstorms normally occur in a year, and of these, 29 strike from May to Aug. Thunderstorms are often accompanied by lightning, wind gusts, squalls and hail, impacting flights during different stages of operations, including takeoff, cruising and landing. When a thunderstorm hits an airport, wind direction changes frequently. A flight cannot take off or land if the wind direction is not uniform. In May 2018, about 70 Delhi-bound flights were diverted — the highest impact of thunderstorms in summer in the past few years. However, in the last month, six major thunderstorms happened in the city, impacting flight operations. On May 2, an intense thunderstorm, accompanied by a squall of 74kmph, diverted three Delhi-bound flights to other cities. Over 500 flights were delayed due to a ripple effect on the network of airlines.

In aviation terminology, a "go-around" describes a safety procedure where pilots abandon their landing attempt and the aircraft ascends back to a safe altitude to either attempt another landing or divert to another airport. Significant impact was seen on May 25 when a thunderstorm diverted 49 flights to other cities. "Of all the weather-related hazards, thunderstorms have the highest impact on aviation across the world. During a thunderstorm, an aircraft experiences turbulence as air currents are unstable, leading to updrafts and downdrafts," said R K Jenamani, senior scientist, IMD. Updraft is a strong column of rising air that can suddenly lift the aircraft while downdraft is a rapid column of sinking air, which often happens after the updraft weakens, causing an aircraft to lose altitude. A study, 'Characteristics of Thunderstorms and Squalls over IGI Airport', which analysed data from 1995 to 2005, found the maximum thunderstorms in June followed by July, and maximum squalls in May followed by June. "More than 80% of thunderstorms in each season are of duration less than three hours, with the remaining mostly 3-6 hours. For pre-monsoon months, the most favourable timing of thunderstorms and squalls is 1200-1500 UTC, while for monsoon, it starts earlier," said the study. Another study, 'Bad Weather and Aircraft Accidents – Global Vis-à-vis Indian Scenario', found 21% of aircraft accidents in India during 1992-2008 were weather-related. Across the globe, it was 26-32%. The study revealed the highest number of these accidents was due to wind-related factors, like gusts, updrafts, downdrafts and low visibility, each responsible for 16% of total weather-related accidents. About 12% of weather-related accidents were due to cumulonimbus and thunderstorms. In the US, 48% was due to bad wind conditions, as found for India, followed by 20.5% due to low visibility and ceiling.

Explainer: What caused IndiGo flight's massive air turbulence?
On Wednesday, an Indigo flight travelling from Delhi to Srinagar encountered severe air turbulence while passing through a thunderstorm mid-air, sparking panic among the 227 passengers on intensity of the turbulence was extraordinary, leading to a distressing experience captured on video by several passengers. The footage—widely shared on social media—shows frightened travelers, some clutching their seats and others praying, as the aircraft shook violently amid the to the alarm was visible damage to the aircraft, most notably a broken nose section. Images of the damage quickly circulated online after the plane landed safely. Though the aircraft touched down without further incident, the episode highlighted the unpredictable and dangerous nature of extreme weather events in WAS THIS INCIDENT SO SEVERE? While turbulence is a common occurrence for frequent flyers, experts say the severity experienced on this Indigo flight was specialists from India Today investigated the cause behind this intense DID THE AIRCRAFT SUDDENLY GAIN AND THEN LOSE ALTITUDE?Turbulence usually occurs due to sudden changes in wind speed or direction—particularly near clouds, storms, or jet streams. In this case, the aircraft encountered a rapidly developing thunderstorm, which produced violent updrafts and downdrafts that significantly disturbed the plane's vertical air movements are common in storm systems and result from uneven heating of the earth's surface, mountainous terrain, and intense storm dynamics. During such events, air can rise or fall at very high the Indigo aircraft experienced an updraft—a rising column of warm air that can lift an aircraft sharply. Normally, pilots try to avoid such systems by rerouting. However, in this situation, downdrafts followed—columns of cooler air descending rapidly, which can push the aircraft downward by thousands of feet. Pilots must exercise great skill to safely navigate these HAPPENS DURING UPDRAFTS AND DOWNDRAFTS?RK Jenamani, a senior scientist at the India Meteorological Department (IMD), explained, 'An updraft is a rising current of air, often found within clouds. These are driven by thermal processes—such as daytime heating—where the sun warms the ground, causing air to rise. Water vapour, being lighter than air, ascends rapidly. Conversely, a downdraft is a sinking column of air, usually triggered by cooling effects like the evaporation of cloud particles, which increases air density and drives it downward.'WHAT HAPPENED TO THE INDIGO FLIGHT MID-AIR?According to experts, the Delhi-Srinagar flight got caught in a strong updraft-downdraft cycle, with vertical air currents possibly displacing the aircraft by 2,000 to 6,000 thunderstorm systems can reach altitudes of up to 3 kilometres, and their intensity often matches the size of the thermal radius. Some experts noted that the flight likely encountered a microburst—a powerful downdraft known for causing severe wind shear and sudden drops in altitude.'During the turbulence, the flight also flew through a hailstorm. As the aircraft ascended, moisture condensed and cooled rapidly, likely forming large hailstones. These hailstones may have damaged the aircraft's nose, as seen in the viral images,' Jenamani THIS SITUATION HAVE BEEN AVOIDED?On the day of the incident, a massive thunderstorm system spanned the northwestern region of India—from Punjab to Uttar Pradesh. Aviation experts emphasise that flying through active thunderstorm zones should always be avoided. In emergencies, pilots typically reroute around such to PTI reports, the Indigo pilot requested permission to enter Pakistani airspace to evade the storm. However, the request was denied, leaving no alternative but to continue through the turbulent the severe conditions, the pilot acted swiftly and maintained a safe altitude, avoiding further complications and ensuring a safe Watch

IMD warns against cyclonic activity near Karnataka; issues pre-monsoon rain alert for Bengaluru, Yadgir and THESE cities
The India Meteorological Department (IMD) warned against cyclonic circulation, near Karnataka, over Arabian Sea from May 21 onwards. IMD predicted that the cyclonic activity would intensify further and would form a low-pressure area at the region around May 22. 'An upper air cyclonic circulation is likely to form over eastcentral Arabian Sea off Karnataka coast around 21st May. Under its influence, a Low-pressure area is likely to form over the same region around 22nd May. Thereafter, it is likely to move northwards and intensify further,' IMD said in its weather forecast dated May 19. On Monday, heavy showers lashed over most of peninsular region, including Tamil Nadu, Karnataka, Kerala, Goa, Telangana and Andhra Pradesh. This rainfall activity occurred due to the prevailing weather systems which are most likely to bring Pre-monsoon downpour in the coming days. Other places where cyclonic circulation was noted include Haryana and Rajasthan, Assam, Maharashtra and Bay of Bengal. Notably, Bengaluru and other parts of Karnataka received very heavy pre-monsoon showers on May 19 that resulted in waterlogging and flooding at several places. As per Bengaluru Meteorological Centre's nowcast warning, precipitation is likely in Kalaburagi, Shivamogga, Vijayapura, Devanagari, Raichur, Yadgir, Ballari, Bengaluru Rural, Bengaluru Urban, Uttara Kannada, Udupi and Dakshina Kannada. Light to moderate rain, thundershowers, lightning and gusty wind speed of 30-40 kmph is likely at isolated places in the next 3 hours, the Meteorological Department said. It forecasted very heavy to heavy rains until May 26 and predicted thunderstorms and lightning with extremely heavy rain until May 21. IMD Senior Scientist RK Jenamani, 'We have issued the orange warning for Karnataka for May 20 and 21. We have issued a red warning for North Interior Karnataka, South Interior Karnataka and coastal Karnataka and adjoining areas of Tamil Nadu... Konkan, Goa and Madhya Maharashtra to get very heavy to extremely heavy rainfall on the night of May 20 or 21st to 22nd,' ANI reported. The IMD official further noted that moderate to heavy rainfall is likely in Mumbai from May 21. The IMD Senior Scientist on May 19 said, 'For North India, there is no chance of a heat wave intensifying... Heat wave warning is only confined to Rajasthan... Parts of South Haryana may have a heat wave... For Delhi, there is no heatwave warning.'
