Tornado (Windstorm in Peshawar) and Next Weather Outlook
Dated: 27th April, 2015
Time: 1200 PST
A mini TORNADO (Twister) hit Peshawar valley with a speed of 110 km/hr and reported rainfall of 60 mm on Sunday evening, causing huge damages. It was very unusual extreme weather event that rarely occur in Pakistan. In the past, same type of windstorms (Tornados) occurred as;
1.In March 2001, in Village “Chak Misran”, Tehsil Bhalwal, District Sargodha with a speed of 193 km/hr, 20 reported dead & 40 injured.
2.In March 2011, in Village “Bahadur Pur”,near Head Marala, District Sialkot with a speed of 100 km/hr, 10 reported dead & 32 injured.
According to the climate of Pakistan, such types of extreme weather events rarely develop due to thermal contrast during the months of March or April (a transition period, when days are getting hot and nights are still cold) due to interaction of cold air mass (from westward) & warm air mas (from east or south).
For Peshawar, “Rain with Dust-Thunderstorm” was predicted two days before (on Friday and Saturday) by PMD but the prediction of tornado or twister is not possible in the world, even today’s advancement in radar and satellite technologies.
The occurrence of such three high impact weather events (extreme) revealed that the consequences of Climate Change, due to deforestation, urbanization & pollution have already happening in Pakistan and the probability of such extreme events would be high in the future.
Weather Outlook for Next 10 days in Peshawar/KPK
Weather is unstable in Pakistan, and two more weather systems are expected to approach upper parts of the country in next 10 days. Scattered rain with dust-thunderstorm is expected in upper KP (Peshawar, Malakand, Mardan and Hazara divisions), North Punjab (Islamabad/Rawalpindi and Sargodha division) and Kashmir during mid of the current week and again during first week of May.
