the wind system associated with a low pressure area in the northern hemisphere is UNANSWERABLE how does this kind of pressure form in an area? In deserts, lack of ground and plant moisture that would normally provide evaporative cooling can lead to intense, rapid solar heating of the lower layers of air. The hot air is less dense than surrounding cooler air. This, combined with the rising of the hot air, results in a low-pressure area called a thermal low. what kind of weather gets associated with his kind of pressure? Windy weather how does it get measured? Anemometer what are the indications of windy weather? the flow of gases on a large scale. has it got any co-relation with rains? Yes - A monsoon is a seasonal prevailing wind that lasts for several months within tropical regions. The big seasonal winds blowing from the Indian Ocean and Arabian Sea in the southwest bringing heavy rainfall to the area of India, Bangladesh, Pakistan etc
