Question

How does humidity of a region affect its weather

Answer 1

In the upper atmosphere, the moisture cools rapidly, forming large clouds that spread out in the reduced pressure conditions. The rapid upward flow of air creates low-pressure areas near the ground, and cooler air rushes in to fill these areas.

Answer 2

Climate refers to the long-term weather phenomena associated with a region. It includes the average temperature, the type and frequency of precipitation and the expected range of variability in the weather. Humidity is both a component of climate and a moderating effect in climate. For example, the tropical rainforest has a climate dictated by its relatively constant exposure to sunlight throughout the year, but the high precipitation caused by high average temperatures is just as much a part of the tropical climate. So separating humidity from climate is not simple, but it's still possible to identify some of the climatological effects of humidity levels
