Mountains can further modify rainy seasons, such as that of the monsoon in South Asia, by obstructing dry air and forcing moist air into the region. Glaciers and Snow: Snow and glaciers on mountains reflect sunlight and keep temperatures cool. When they melt, they can flood nearby areas with water. Microclimates: The mountains are capable of creating microclimates, having small, different climates in one area, thereby making weather more extreme or variable. In short, the mountain ranges disrupt winds and make rain or dryness, alter the temperature, and create different climates at higher elevation.
