Near the Earth’s equator, solar heating is intense year round. The Sun heats the ocean, evaporating tremendous amounts of water. ... As air rises, it cools, and water vapor condenses into rain . This daily cycle of heating, evaporation, and convection creates a persistent band of showers and storms around Earth’s middle.
Why does it rain almost everyday in the equatorial region?
Answer: This is due to planetary belts and the movement of moisture-laden wind through different regions of the equatorial region. There are winds from two different directions which meet at the equator. ... The air meanwhile gets condensed and it falls as rainfall along the equator.
Why does it rain so much at the equator quizlet?
The warm air can hold large amounts of water that evaporate from the equatorial oceans and land. As the warm air rises it cools, which reduces some of its ability to hold water. Areas near the equator receive large amounts of rain. Cool water over the equator cannot sink because hot air is rising below the cool air.
Why is there so much rain in the tropics?
As the sun shines strongly on the tropics — particularly on the warm oceans which have an effectively infinite amount of water to evaporate into the air — the overlying atmosphere becomes very humid. ... If enough water condenses , the cloud droplets can become large enough to fall as rain.
Which region has the highest amount of precipitation?
The regions of highest rainfall are found in the equatorial zone and the monsoon area of Southeast Asia . Middle latitudes receive moderate amounts of precipitation, but little falls in the desert regions of the subtropics and around the poles.
In which months does it rain at the equator?
The rainfall varies locally with the wettest months of the year occurring from November to January and the driest period from June to July (Oldeman, 1978). The daily evapotranspiration rate on land (lower than 4.34 mm) can be slightly more than that on open waters (4.12–4.2 mm).
Why are temperatures warmer at the equator that at the poles?
Why is it hot at the Equator and cold at the poles? Due to the tilt of the Earth, the Equator is closer to the sun so receives more of its energy . The Equator has a smaller surface area so heats up quickly compared to the poles. There is less atmosphere to pass through at the Equator compared to the poles.
What happens to warm air when it cools quizlet?
– List the steps in atmospheric circulation. Warm air can hold more water vapor than cold air can. Warm air cools: water vapor that it contains may condense into liquid water to form rain, snow or fog.
What is the pattern of weather over a long period of time?
In short, climate is the description of the long-term pattern of weather in a particular area. Some scientists define climate as the average weather for a particular region and time period, usually taken over 30-years.
Which month does it rain at the Tropic of Capricorn?
From April to September , the rain belt lies in the northern hemisphere, and a wet season occurs there, while the southern tropics experience their dry season. The rain belt reaches roughly as far north as the Tropic of Cancer and as far south as the Tropic of Capricorn in the western Pacific Ocean.
Why tropical countries are hot?
This is because as the dry air descends from high altitudes, its compression leads to an increase in its temperature . ... Therefore, air temperature in the tropics (42 degrees Celsius) is greater than that of the Equator (30 degrees Celsius). This is why tropical regions are hotter than the Equator.
Why tropical region is hot?
The tropics are warm all year, averaging 25 to 28 degrees Celsius (77 to 82 degrees Fahrenheit). This is because the tropics get more exposure to the sun . Because of all that sun, the tropics don’t experience the kind of seasons the rest of the Earth does. ... Other areas in the tropics have a drier climate.
What is the rainiest city in America?
Mobile is the rainiest city in the United States. Mobile receives an average annual rainfall of 67 inches and has about 59 rainy days per year. Located on the Gulf of Mexico, Mobile’s winters tend to be mild and rainy, and the area is subjected to tropical storms and hurricanes during hurricane season.
What’s the rainiest city in the world?
The remote city of Quibdó is sometimes cited as the rainiest in the world, with average rainfall of 7,328mm a year, according to one estimate from local weather station data.
