Places with an equatorial climate are mostly located in South America, rivers in Africa and South east of Asia. The annual rainfall in these places are of 2000 mm because of thunderstorms during the afternoon. This heavy rain occurs due to the concentration of warm air which creates an area of low pressure. This climate has a high level of humidity, a lack of seasonal change and a daily pattern.
A daily pattern is a proves where the sun heat evaporates moisture from the previous rain. Temperatures are 25°C and when the sun is on a vertical position, they are 33°C. Rising air cools and reachs higher attitudes. The large cummulus clouds produce torrential downpours, lighting and thunder. Clouds stars to break up by the sunset do nights are humid and warm. Places have 12 hours of daylight and 12 hours of darkness.
Tropical continental climates are located between latitudes 5° and 15° north and south of the Equator. This climate has wet and dry seasons due to the constant movement of the overhead sun. When the sun takes a more vertical position, temperatures rise and they decrease when the clouds cover the sun and rainfall appears (July and August).
Monsoon, with means "season", have the south west monsoon and the north east monsoon.
• The south west monsoon is when the sun is overhead in the Tropic of Cancer (June). When the air becomes hotter on a place, in this case in the north of Himalayas, it's formed an area with low pressure. Air rises overt the mountains and gives relief rainfall.
• The north east monsoon, places (north of Himalaya) become cold and there is an area of high pressure. Winds give little rain as they cross India.
Hot desert are mostly located in the west coast of continents, South America, Africa, Australia, Mexico, close to the tropics and cold ocean. This places have high evotranspiration. When the sun is overhead, hot temperatures increases and they decrease when the sun is in the opposite. There is scace precipitation because;
• Winds blow from dry areas.
• Winds have to cross mountains.
• Air that rise in the equator descends in the latitudes.
• Winds from the sea are cool and unable to pick up moisture.
Cold climates are formed mostly in Eurasia, Scandinavia, Rusia, North America, Alaska and Canada.
This climates have long and dark winters which are cold partly due to the location in the latitude and partly due to the lack of influence of the sea.
In this type of climate summers are short but warm, because of the daylight and because of the location far away from the sea.
Precipitation is light and falls as snow because air is too cold to hold moisture.
