NOTES

Temperate Cyclones : These may becircular, elliptical contrasting air masses e.g. warm, moist and light tropical air masses (westerly winds) and cold and dense polar air masses. After their formation, temperate cyclones move in easterly direction under the influence of westerly winds and control theweather conditions in the middle latitudes. The path followed by these cyclones is called 'Storm Track'.

2.         Tropical Cyclones: This type of cyclones developed in the regions lying between the Tropics of Cancer and Capricorn are called Tropical cyclones. The weather conditions of low latitudes mainly rainfall regimes are largely controlled by tropical cyclones. Tropical cyclones usually develop in summer season in the vicinity of Inter-Tropical Convergence Zone (ITCZ) over warm ocean surf
