The temperate zone Between the 45° and the 60° on both hemisphere MAT is between 12°C and -10°C MAR is great 4 seasons Dominated by west winds 4 climate areas: Marine climate area Continental climate area semi-arid and arid climate area Subarctic climate area
The marine climate area West coast of contintents MAT : 8-10°C MAR: low , 7-8°C Precipitation : even and aboundant , around 1500mm/ year eluviation Dominated winds : westerly winds Seasons : cold , humid summer and mild , humid winter Water output and water level : even Landform processes : chemical weathering , work of rivers
Natural vegetation : deciduous forest ( oak and beech ), peat bogs Soil : brown forest soil ( rich in humus , intensive eluviation )
The continental climate area Subtypes : Continental warm summer – mean temp.of the warmest month exceeds 20°C Continental cool summer – mean temp . of warmest month doesnt exceed 20°C Continental monsoon areas MAT: depends on the latitude , around 10°C MAR: 24-25°C Winds : west winds , cyclones Soil : brown forest soil Landform processes : chemical and mechanical weathering
Vegetation : deciduous forest , mixture of steppes and trees less prec . Seasons : 4 seasons , warm or hot summer and cold winter Precipitation : 5-800mm, very uneven , maximum in summer Water output and water level : uneven
Continental monsoon climate area East Asia very cold winter , warm summer abundant precipitation
Semi-arid climate areas MAT : 0-10°C MAR : 24-25°C Precipitation :3-500mm, uneven Winds : weaken west winds Landform processes : mechanical weathering ( frost shattering ), erosion of winds Water level and water output: uneven Seasons : 4, warm or hot summer and col or very cold winter
Vegetation : grasslands Steppe Pampas P rairie Soil : chernozem – black , high humus content , slow eluviation
Arid climate areas Deserts and semi-deserts Great distance from the oceas MAT: 0-10°C MAR: 40-50°C Precipitation : less than 300mm Winds : local winds Vegetation : poor poor soil No constant rivers Landform processes : mechanical weathering , work of wind
The subarctic climate area MAT: -10-0°C MAR: 50-60°C Precipitation : 300mm Winds : westerly and polar easterly winds Seasons : 4, short and relatively warm summer and long , cold winter Rivers : forzen during 8-9 months Landform processes : frost shattering , land slides
