The sub – tropical high – pressure belt is found between 30°-35° latitude in both the hemispheres. In this belt, the condition of high temperature, high air pressure and cloudless sky is seen throughout the year. The main feature of this air pressure belt is the presence of all the hot deserts of the world on the western edges of the continents in this belt.
With the absence of friction in the upper part of the atmosphere, these winds turn towards their right and left, in the northern and southern hemisphere respectively. These regions of high pressure are also known as Horse Latitudes. This air pressure belt is considered to be a dynamic belt. In this belt, except for the winter season, the temperature is found to be high. In both the heme spheres, the high pressure centers are found on the oceans in summer. Due to the descending air, the atmosphere remains calm in this belt.
