Transcript of Three Types of Climate

Three Types of Climate The monsoon 'a season' Mediterranean Cold Climates South-west monsoon North-east monsoon - during the winter, overhead sun moves southward
- very cold + high pressure
- originate in a dry area
- small amount of rain
- end of dry season = risk of drought - sun appears to be over head at the Tropic of Cancer during June
- extremely hot
- low pressure and warm
- air is forced to rise over mountains
- large amounts of relief rainfall
- rain can caused extensive flooding, while the north remain dry - between latitudes 30 and 40 north and south of the Equator
- hot, dry summers and war, wet winters
- summers are hot = sun is at a high angle and prevailing winds blow from warmland
- occasional thunderstorm + dry and sunny weather
- winters are warm = sun is lower, still higher than places further from Equator and prevailing wind reversed direction but from sea
- make caostal area warm and moist air
- large amount of rainfall
- poleward side of 60 N in Eurasia
- large annual range in temperature
- winters are very long, dark, and extremely cold
- strong winds = lower temperature + increase the wind-chill factor and risk of frost-bite
- summers are short but warm
- precipitation is light
- snow and blizzards in winter
convectional rainstorms in summer
Tropical cyclones (hurricanes) Formation Effects - over warm tropical oceans, 27 C over a vast area, and considerable depth of warm water
- late and early autumn = sea temp. at highest
- trade wind belt between latitudes 5 and 20 north and south of the Equator
- as air rises + spiral movement + cools + condenses = huge amount of heat energy
- hard to predict
- colder air sinks downward inside the centre of the hurricane to form a central eye
- reaches land, source of heat energy + moisture is removed and strength decreases
- lifespan 7 - 14 days winds - exceed 160 km/hr can reach 250 km/hr
- lie in the tropical cyclone belt
- severe damaged flooding - caused by the torrentia rain = pollute water supplies, risk of cholera Storm (tidal) surges - up to 5 m by storm waves, flood low-lying coastal areas
- cause loss of life + blocking escape + relie roads Landslides - occur where heavy rainfall
- make buildings breakdown and unstable slopes
