Where does rainfall usually occur?
tropics
The water vapor stays in the atmosphere until it cools and condenses, first into clouds and then into raindrops. How hard it can rain depends on the amount of moisture in the air. The atmosphere holds more water if it’s warm, that’s why most places that set rainfall records are in the tropics.
What phase does rain occur?
Water vapor is an invisible gas in our atmosphere. Water vapor can condense in the atmosphere as clouds. When the water vapor in clouds cools, it can condense into a liquid and fall as rain or freeze into a solid and fall as snow or ice crystals.
What time of year does it rain most?
While spring and winter often feature many days with precipitation, totals are generally higher during the summer months when warmer temperatures allow the air to hold more moisture.
What causes rainfall?
Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. When it evaporates—that is, rises from Earth’s surface into the atmosphere—water is in the form of a gas, water vapor.
How are the 3 types of rainfall formed?
The causes of relief rainfall, frontal rainfall and conventional rainfall are examined. Relief rainfall occurs when air has been blown over the sea and is then forced up over an area of high land.
How rainfall is formed?
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. Most rain actually begins as snow high in the clouds. As the snowflakes fall through warmer air, they become raindrops.
What are the 4 stages of the water cycle?
There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam. The water vapour or steam leaves the river, lake or ocean and goes into the air.
Which month has the most rainfall?
His conclusion is that June is, overall, most frequently the wettest month in the U.S. with 2,053 of the 8,535 sites reporting such.
Does it rain more in the spring?
Spring is the rainiest season of the year in terms of the number of days with precipitation. Spring is the rainiest season in the Northern Hemisphere because warmer air can hold more moisture than colder air, and the air gets warmer during the spring.
What are the 3 main causes of rainfall?
There are 3 main types of rainfall: relief, frontal and…
- Occurs mostly in tropics where it is hot.
- When air is hot is rises and cools and condenses forming rain.
- If the air is hot enough, it rises very quickly and can cause thunderstorms.
