The term was first used in English in British India (now India, Bangladesh and Pakistan) and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. Monsoons may be considered as large-scale sea breezes, due to seasonal heating and the resulting development of a thermal low over a continental landmass. They are caused by the larger amplitude of the seasonal cycle of land temperature compared to that of nearby oceans. In winter, the land cools off quickly, but the ocean retains heat longer. The cold air over the land creates a high pressure area which produces a breeze from land to ocean. Monsoons are similar to sea and land breezes, a term usually referring to the localized, daily cycle of circulation near coastlines, but they are much larger in scale, stronger and seasonal.
The summer monsoons roar onto the subcontinent from the southwest. The winds carry moisture from the Indian Ocean and bring heavy rains from June to September. The torrential rainstorms often cause violent landslides. Entire villages have been swept away during monsoon rains. Despite the potential for destruction, the summer monsoons are warmly welcomed in Pakistan. Farmers depend on the rains for their land irrigation. Additionally, a great deal of Pakistan’s electricity is generated by water power provided by the monsoon rains. Foreign people come from abroad to visit Pakistan in the month of August during the monsoon season because the atmosphere is quite pleasant during that time. So, there is still a room of improvement present to avail such a blessing opportunity in right way.
Moreover, Floods in Pakistan are mainly caused by the heavy monsoon rains during the summer monsoon period from July to September. Information on heavy rainfall generating meteorological situations assisted in accurately calculating peak discharges of river flows at designated sites in Pakistan. This contributed to saving life, cattle and property by issuing timely forecasts / warnings to Government agencies responsible for Flood Relief evacuation and mitigation for the people living in the flood plains. In this season the common diseases faced by people are as URTI (Upper Respiratory Tract Infection), LRTI (Lower Respiratory Tract Infection), AD (Acute Diarrhea), SCB (Scabies), and UF (Unexplained Fever). While Malaria, Gastro, and jaundice cases are also exist. Hepatitis B & C can be grow in such a living style mean no cleanliness, unhygienic food stuff & poor availability of proper medicines on time.
