The local weather of Pakistan has historically been outlined dependent both on the four seasons that is summer season, winter season, spring and slide or in conditions of Pre monsoon, Monsoon, Put up monsoon and winter as defined by Meteorological corporations in South Asia. The climatic features of the place, nevertheless are as well numerous and advanced to conform to the above pointed out nomenclatures.
There is a dire have to have to redefine the climatic zones based mostly on hard cash crop output Pakistan remaining an agro-centered economy. For this goal subsequent climatic Zones are proposed:
The Rain Fed or Barani Zone
This is a narrow strip like zone in Northern Pakistan that is composed of about 10 % of the whole land spot of Pakistan and includes of Rawalpindi, Hazara, Gujranwala divisions and Kashmir. The basic climatic functions are absence of any extended heat spell, average temperatures both in summer months and wintertime when compared to other places of Pakistan, no prolonged hygrothermal anxiety for crops and responsible rainfall all the 12 months spherical. This space is so found geographically that it will get profit the two from the western disturbance and the monsoon programs.
The Canal Fed Zone
This zone is composed of the higher and lessen Indus Basic. The normal climatic capabilities are cool winters and exceptionally scorching summers with reasonable to superior hygrothermal worry to cash crops. The rainfall is not very deficient but is inappropriate to guidance crops on its own. So the deficit is met with the outstanding canal procedure present in the space. This climatic zone accounts for 30 % of the total location of Pakistan.
The Arid North and North West Zone
This consist of entire of the Baluchistan plateau, and dry mountains of the North and North West. The standard characteristics are extreme dryness, extreme wintertime chilly, a full absence of monsoon rain tumble and higher hygrothermal stress for the crops. In point the temperatures and the humidity figures achieve to such an extreme to render any type of agriculture activity pretty much difficult. This climatic zone accounts for 55 percent of the overall land location of Pakistan.
The Arid Coastal Zone
This consist of a extremely slim area together the southern coastline of Pakistan that accounts for 5 per cent of the full land spot of Pakistan. There is basically no rainfall each in winter season and summer season. The humidity is large all over the yr. The temperatures continue being higher all through the 12 months. There is no canal process in the space and no fresh drinking water resource is situated nearby. This location is also not in good shape for any form of agriculture.
In shorter, a strong requirements exists to redefine the climatic zones of Pakistan based mostly on agriculture Pakistan being an agro-based mostly economic system.
