Pakistan is located on a great landmass north of the tropic of cancer (between latitudes 25° and 35° N), it has a continental type of climate characterized by extreme variations of temperature, both seasonally and daily. Pakistan has recorded one of the highest temperatures in the world – 53.5 °C (128.3 °F) – on 26 May, 2010. It is not only the hottest temperature ever recorded in Pakistan, but also the hottest reliably measured temperature ever recorded in the continent of Asia. In the rest of the country, temperatures reach great heights in the summer; the mean temperature during June is 38 °C (100 °F) in the plains, the highest temperatures can exceed 47 °C (117 °F). In the summer, hot winds called “Loo” blow across the plains during the day. The dry, hot weather is broken occasionally by dust storms and thunderstorms that temporarily lower the temperature.
According to the recent weather forecasts, provided by Assistant Meteorologist ,the present intensity of the heat waves are expected to continue for the next one week. He also predicted that dust storms and drizzling may reduce the intensity of the brazen heat, in Islamabad, Northern Punjab, Northern areas of KPK, Gilgit Baltistan and Kashmir. Another finding of his analysis, is the reduction in wind pressure across Arabian Sea, flowing North West, and signifying the prevalence of intense heat currents ,diffusing from the South up to the North of Pakistan.
Pakistan Meteorological Department has also forecasted an incredible rise in the waters of of Gilgit and Kashmir, thereby causing increase in the water-intake of Tarbela Dam. Besides,it is expected that unstable weather conditions will continue to prevail in the country during the current low-rain month, generating frequent rain and dust storms to the detriment of crops.
Global warming is the phenomenon that is new to our ears. One of its horrifying consequences is the increase in the average temperature rise in the world temperature, making Pakistan more susceptible to them, owing to country’s geographical location. Besides, staggering rate of deforestation to provide for the rapid population giant, is disturbing the natural Water Cycle. This, in turn, minimizes the average rainfall to a disappointingly low.
Nevertheless, South Western Monsoon occurs in summer from the month of June till September in almost the entire country. Monsoon rains bring much awaited relief from the scorching summer heat. These monsoon rains are quite heavy by nature and can cause significant flooding, even severe flooding if they interact with westerly waves in the upper parts of the country. And this is the predicament, we have been facing, immensely, since 2010 devastating floods. Paucity of water storage reservoirs, and substantial melting of snow-capped peaks and glaciers, in the Northern Areas of Pakistan, due to rapid deforestation and global warming, are the catalytic factors.
