Abstract:
In this report, changes in the rainfall activity, minimum, maximum and mean temperatures have been studied on monthly as well as on seasonal basis during the winter season (January-March) 2010 in Khyber Pakhtoonkhwa of Pakistan. The data was collected from 11 meteorological observatories located in Khyber Pakhtoonkhwa. By comparing the monthly data of rainfall, minimum, maximum and mean temperatures for the winter months of the year 2010 with the climatic normal values of 1971-2000, it has been found that the rainfall was moderately below normal during the month of January, largely above normal during February and largely below normal during the month of March. As a whole, seasonal rainfall remained normal during the winter season across the region due to the large scale global circulations. Consequently, scanty rainfall distribution during the season resulted in a bad crop conditions. As a whole, the minimum and maximum temperature remained slightly above normal during the winter season throughout the region. Consequently the mean temperature also remained slightly above normal during the study period across the region. The possible reason for this may be abnormal approach of western disturbance, position Tibetan high pressure system or frequent changes in El Nino and La Nina conditions.
