7 factors affecting the climatic conditions of the world

Climate is average weather condition recorded over a long period of time for example 30 years.

The following are factors affecting climate:

  • Distance from large water bodies. This influence temperature and rainfall. Places near the sea or ocean have higher temperatures and receive more rainfall than places that are inland due to high rate of evaporation. For example coastal regions experience high temperature and rainfall than inland areas
  • Aspect. This refer to the direction in which slopes faces. it affect temperature and rainfall. For example, in higher latitude in the northern hemisphere, southern facing slopes  are warmer than than northern facing slopes, in southern hemisphere, northern facing slopes are warmer than southern facing slopes. Also the windward slope of highlands generally receive high rainfall than leeward slopes
  • Distance from the equator
  • Altitude. This influence temperature and atmospheric pressure of the area. Low altitude areas are warmer than high altitude areas and atmospheric pressure is lower at high altitude than at high altitude

  • Human influence
  • Ocean currents. Wind blowing over the ocean adopts the temperature of currents and carry this influence to the region next to the ocean. This either reduces or increases the temperature on land depending on the nature of ocean currents. Winds blowing over cold ocean currents bring little or no rainfall to the land while those  which blow over warm ocean currents carry moisture that causes a lot of rain over the land

  • Alignment of the coastline. Alignment means the arrangement of the region’s coastline in relation to the direction of the wind. Where winds blow parallel to the coastline they usually cause drought. Where they blow across the coastline they cause the rainfall
  • Wind and air masses. The wind carries heat and moisture as it blows. If the wind is blowing from a warm region, it warms the region over which it is blowing. If the wind is cool, it cools the region over which it is blowing, causing the temperature of the area to fall. Moist wind cause rain over their destination regions while dry wind enhance drought
