Mumbai Weather:

Taking stock of the Mumbai local weather this year,shows a warm trend and frequent "heat waves" during winter. Again,today the temperature has risen to 36°c at Santacruz,and 35°c at Colaba.Santacruz was 36°c,which is 4°c above,for the fourth day running !Now,this has frequented too often this winter.In the attached graph of Mumbai,the first diagram of the last 30 days shows a big patch of red(above normal),and that too for most of the days.The second diagram indicates that the average temperature this time in Jan/Feb has been above normal by almost 2°c ! And that means considerably warmer than usual !

Even the nights are far too warm for comfort.The minimum was 24°c,which is 7°c above !

Infact,the entire Gujarat and Maharashtra region has heated up,with the hottest spot today being Baroda and Surat at 37°c.The heated area is clearly seen in the map.

Mumbai is hot due to strong inland winds,and lack of northerly winds.The winds should reverse from the 24/25th.of Feb.Whatever the reasons,the city has been deprived of any meaningful winter this season.

Paraglider swept into thunderstorm :
"Severe thunderstorms over southern and eastern states in Australia have caused serious and in some cases tragic consequences for Paragliders, who have been training for the world paragliding championships.
A German champion paraglider was sucked into a powerful thunderstorm earlier this week. She was swept over 32, 000 feet above sea level, which is higher than Mount Everest, into the eye of the storm, near Manila in New South Wales. This all happened in about 15 minutes due to the strong updraughts inside the Cumulonimbus cloud (specific clouds associated with thunderstorms). The glider moved with a speed of 20 m/s (39 mph) whilst ascending within the cloud and the powerful downdraughts brought her down at 30 m/s (58 mph). Cumulonimbus clouds are fuelled by vigorous convective updraughts (sometimes in excess of 58 mph); the tops of the clouds can easily reach 39, 000 feet. Large thunderstorms have deep rotating updraughts and can have a lifetime of several hours. They can produce frequent lightning, large hail, damaging winds and tornadoes. The sportswoman was unconscious for part of this remarkable ‘flight’ but when she awoke she was aware of lightning and heard thunder all around her. It is amazing that she survived this ordeal. Not surprisingly she suffered frostbite to her face, as temperatures near the top of the cloud would have been as low as minus 50 degrees Celsius. The combination of moisture and very low temperatures cocooned the glider in ice. She also endured abrasions on her legs from large, pelting hailstones."

A very interesting fact I borrowed from Jim:
"Nepal, where Kathmandu, its capital city, had rare snow Wednesday_14th.feb. There were drenching thunderstorms along the Himalayan foothills (amongst which the city lies) and it must have been towards the hed of these rains (late in the day) that rain turned to wet snow or even small, soft hail. Whatever, the cold, white stuff lay on the ground, reportedly for the first time in more than 60 years."
Even Darjeeling in W.Bengal had snow,after 2 years,and a minimum of -2°c.

There have been thunderstorms here this week much as one would expect in early March rather than the dry months of winter. At Chittagong, Bangladesh, rainfall on Monday into Tuesday was 84 mm. This is almost as much rain as normally falls in the first three months of the year. Today, 40mm downpour hit Balasore, Orissa, more than one February`s worth of rain.
These rains result from the above-normal warmth that has settled over the Subcontinent this month together with a strong sub-tropical jet stream which has dipped southward over Bangladesh and eastern India.

A trough and cold front will shift to western Pakistan by the 9th (Friday) and to the northern Subcontinent on the 10th and 11th. This will bring the first widespread rains (thunderstorms, mountain snows) in weeks to Aghanistan, Pakistan and northern India. The result will be a cold wave ,on sunday/Monday in N.India and Central India(including Maharashtra and Gujarat).
