What causes rain?

Rain occurs when air rises into the upper atmosphere and cools. The cool temperatures cause water vapor to condense into water droplets, which fall from the clouds as rain when the air becomes saturated.

What is the main cause of rain?

Clouds are made up of tiny water droplets. When these droplets grow, they eventually become too heavy to stay suspended in the sky and fall to the ground as rain. Some droplets fall through the cloud and coalesce into raindrops on their way down.

What causes rain to fall as water?

Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the earth. If a cloud is colder, like it would be at higher altitudes, the water droplets may freeze to form ice.

What will happen if there is no rain?

If there is no rain for a long period or for many years, then there is scarcity of water in that region. This leads to drought. The lack of adequate precipitation, either rain or snow, can cause reduced soil moisture or groundwater , diminished stream flow, crop damage, and a general water shortage.

One reason is the top of the clouds cool during the night, allowing the air mass to reach its dew point more readily and producing greater amounts of precipitation.

Why is it hot before rain?

When warm humid air flows into cool air the humidity is condensed into rain as the warm air cools. The temperature rise your feeling is the warm humid air rolling into your cooler area before it rains. Your body cools itself by sweat evaporating which disperses your heat into the surrounding atmosphere.

What causes rain at night?

The air heats up during the day, and collects as much moisture as it can hold at that temperature. At night it cools down and can no longer hold the moisture, so it rains out.

Rain is rare at temperatures above 100°F

It is rare to get rain when the temperature rises above 100°F (38°C), since heat of that intensity is usually accompanied by a high pressure system with sinking air, which discourages clouds and rainfall.
