Some mountains are so high that its peak is hidden behind clouds. Enormous mountain weather turnsaffects. When the moving air hit the slopes, the air forced upward. At the time that the temperature risedown, and the clouds are formed. Hot air is forced to rise up to the top of the mountain side. At some level,a lower temperature causes the water to form clouds.

Virga occurs when rainfall reaches a layer of dry air. Water droplets rain turns back into water vapor in the air, and disappeared. Most rainwater never reaches the ground. Droplets of rain water vapor turns back into water due to hit a layer of very dry air towards justice. You can actually see the grains that fell like a curtain of clouds, but stopped in mid-air, this type of weather is called virga.


Swallow hot clouds and the earth's temperature to maintain order. Of every 2 square meters of land, the cloud is able to move the same amount of energy as that generated by the powerful 60 watt light bulb. Clouds appear in all shapes and sizes. To help recognize, scientists divide the clouds into ten basic types. Types of clouds depends on the form of clouds and where the clouds formed in the sky. Cirrus clouds looked like a wisp of smoke. These clouds are formed high in the troposphere and rarely produce rain, clouds sratus form in flat layers and produce drizzle and the rain snow. Cumulus clouds bring heavy rain and storms. clouds that look like a huge cauliflower looks soft and smooth, but it will feel wet to the touch.
