- GULF TYPE CLIMATE & NATAL TYPE CLIMATE
UNIT 4 – CLIMATOLOGY – PART 39
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.
