Climate: is the average of all weather conditions if An area over a long period of time. The The main factors that influence temperature are latitude, altitude, distance from a large body of water, and ocean currents. Latitude: Latitude: is the distance from the equator, measured in degrees Earth’s surface can be divided into 3 temperature zones.
Tropical Zone Located near the equator between 23.5 north latitude and 23.5 south latitude. Located near the equator between 23.5 north latitude and 23.5 south latitude. It receives direct or nearly direct sunlight all year around. It receives direct or nearly direct sunlight all year around. Climate is warm. Climate is warm. Polar Zone It extends from 66.5 to 90 north or south latitude. It extends from 66.5 to 90 north or south latitude. The sun’s rays strike at a lower angle neat the north and south poles. The sun’s rays strike at a lower angle neat the north and south poles. Climate is cold. Climate is cold. Temperate Zone It is located between the tropical and polar zones. It is located between the tropical and polar zones. Located 23.5 to 66.5 north or south latitude. Located 23.5 to 66.5 north or south latitude. In the summer, the sun’s rays strike the zone more directly. In the summer, the sun’s rays strike the zone more directly. In the winter, the rays strike at a lower angle. In the winter, the rays strike at a lower angle. Climate is warm to hot in the summer and cool to cold in the winter. Climate is warm to hot in the summer and cool to cold in the winter.
Altitude: Why does a mountain have polar caps if they are located in the tropical zone? Temperature of the troposphere decreases about 6.5 degrees Celsius for every 1km increase in altitude. Therefore highland areas everywhere have cool climates no matter what their latitude.
Distance from a Large Body of Water Water Water heats up more slowly than land; it also cools down more slowly. Therefore, winds from the ocean keep coastal regions from reaching extremes of hot and cold.
Ocean Currents Warm Warm ocean currents carry warm water from the tropics toward the poles. Cold currents bring cold water from the polar zones toward the equator. The surface of the water warms or cools the air above it. The warmed or cooled air then moves over the nearby land. So a warm current brings warm air to the land it touches. A cold current brings cool air.
Humid Tropical FFFFound near the equator TTTTemperature is always 64 degrees F or higher.
Tropical Wet Always hot and humid Heavy rain, at least 6cm a month all year around. Lush vegetation Ex. Amazon rain forest in South America.
Tropical Wet-Dry Always hot Alternating wet and dry seasons Heavy rainfall Tropical grassland Ex. Miami, Florida
Dry EEEEvaporation is greater than precipitation. MMMMay be cold or hot IIIInland from the ocean
Desert DDDDesert (hot and sandy or cold and rocky) GGGGets less than 25cm of rain all year IIIIncludes hottest places on Earth. IIIIn most deserts high daytime temperatures lead to rapid evaporation. EEEEx. Phoenix, Arizona
Semiarid Edge of the desert prairies or grasslands Great plains Receive about 25- 50cm of precipitation all year. Ex. Denver, Colorado
Moist Mid-latitude with Mild Winters AAAAverage Temperature 50 degrees F or above in the warm months BBBBetween 26-64 degrees F in the coldest months
Mediterranean WWWWarm, dry summers RRRRainy winters DDDDense shrubs and small trees OOOOlives and grapes SSSSome coastal areas have cool summers and frequent fog. EEEEx. San Fransico, California
Humid Subtropical Hot, muggy summers Cool Mild winters Southeast United States Mix forests Precipitation fairly even throughout the year. Ex. Charlotte, North carolina
Marine West Coast MMMMild Winters (rainy) CCCCool summers MMMModerate precipitation due to coastal region. CCCCone bearing trees LLLLow clouds and fog. EEEEx. Seattle, Washington
Mid-latitude with Severe winters AAAAverage Temperature 50 degree F or above in warm months 22226 degrees F or below in the coldest months
Humid Continental Bitterly cold winters Warm humid summers Moderate rainfall year around Northeastern United States Our Climate
Subartic Summer short and cool Winter long and bitterly cold Light precipitation in summer Ex. Russia, Canada, and Alaska
Polar AAAAverage Temperature is always below 26 degrees F even in the warm months NNNNear Poles
Ice Cap Average Temperature is always at or below freezing. Covered with snow and ice Intense cold makes the air dry Ex. Greenland and Antarctica.
Tundra Short cold summers Bitterly cold winters Frozen soil (no tree or plant growth) Warmest temperature about 26 degrees F.
Highlands Temperature Temperature drops as altitude increases mountain region can contain many climates. Mountain Mountain can have a year round covering of ice and snow at their peaks Ex. Ex. Rocky Mountains
