CHINA TYPE CLIMATE, GULF TYPE CLIMATE & NATAL TYPE CLIMATE


Different variants of Warm Temperate Eastern Margin Climate include the

Temperate monsoon Climate or China Type Climate,

Gulf Type Climate and Natal type climate

Found between 20° and 35° N and S latitude (warm temperate latitudes just outside the tropics); on the east coast in both hemispheres.


CHINA TYPE CLIMATE


Temperate Monsoon or China Type climate is observed in most parts of China. The climate is also observed in Southern Parts Of Japan.


GULF TYPE CLIMATE


Found in south-eastern U.S.A., bordering the Gulf of Mexico where continental heating in summer induces an inflow of air from the cooler Atlantic Ocean.

NATAL TYPE CLIMATE

Found in in New South Wales (Australia), Natal (South Africa), Parana-Paraguay-Uruguay basin (South America).

Natal type is different from temperate monsoon or China type as it receives rainfall from on-shore Trade Winds all the year round.

CLIMATE 

Characterized by a warm moist summer and a cool, dry winter (one exception: winters are also moist in Natal Type).

TEMPERATURE

The mean monthly temperature varies between 4° C and 25° C and is strongly modified by maritime influence.

Occasionally, the penetration of cold air (Polar Vortex) from the continental interiors may bring down the temperature to freezing point.

Though frosts are rare they occasionally occur in the colder interiors.

PRECIPITATION

Rainfall is more than moderate, anything from 60 cm to 150 cm.

This is adequate for all agricultural purposes and hence supports a wide range of crops.

Areas which experience this climate are very densely populated.

There is the fairly uniform distribution of rainfall throughout the year.

Rain comes either from convectional sources or as orographic rain in summer, or from depressions in prolonged showers in winter.

In summer, the regions are under the influence of moist, maritime airflow from the subtropical anticyclonic cells.

Local storms, e.g. typhoons (tropical cyclones), and hurricanes, also occur.

Variations of Warm Temperate Eastern Margin Climate

CLIMATE TYPE

Feature

China type               Temperate monsoonal

Gulf type               Slight-monsoonal

Natal type               Non-monsoonal

CHINA TYPE CLIMATE

SUMMER

Intense heating within interiors (Tibet, desert region) sets up a region of low pressure in summer attracting tropical Pacific air stream (South-East Monsoon).

Monsoon does not ‘burst’ as suddenly, nor ‘pour’ as heavily as in India.

Typhoons form mostly in late summer, from July to September.

WINTER

In winter, there is intense pressure over Siberia and the continental polar air stream flows outwards as the North-West Monsoon, bitterly cold and very dry.

There is little rain but considerable snow on the windward slopes.

Another climatic feature associated with the China type of climate in southern China is the occurrence of typhoons.

GULF TYPE CLIMATE

Monsoonal characteristics are less intense compared to China type.

There is no complete seasonal wind reversal.

Hurricanes occur in September and October.

NATAL TYPE CLIMATE

The narrowness of the continents and the dominance of maritime influence eliminate the monsoonal elements.

The South-East Trade Winds bring about a more even distribution of rainfall throughout the year.
