What are the factors that affect the climate?
3.1 Factors affecting climate
- distance from the sea.
- ocean currents.
- direction of prevailing winds.
- shape of the land (known as ‘relief’ or ‘topography’)
- distance from the equator.
- the El Niño phenomenon.
What are two topographic features that cause variations in climate?
The effects of topography on the climate of any given region are powerful. Mountain ranges create barriers that alter wind and precipitation patterns. Topographical features such as narrow canyons channel and amplify winds. Mountains and plateaus are exposed to the cooler temperatures of higher altitudes.
What are some limits associated with the use of normal?
What are some limits associated with the use of normal? When climate normals are based on airport data, they might differ from actual weather conditions in nearby cities. Changes in elevation and other factors, such as proximity to large bodies of water, can cause climates to vary.
Which two factors have the greatest effect on climate?
On the surface, the greatest factor affecting Earth is sunlight. Sun provides energy for living organisms, and it drives our planet’s weather and climate by creating temperature gradients in the atmosphere and oceans.
What are two most important factors in defining a climate region?
The two most important factors in the climate of an area are temperature and precipitation. The yearly average temperature of the area is obviously important, but the yearly range in temperature is also important. Some areas have a much larger range between highest and lowest temperature than other areas.
Why do climates vary?
Climate varies from region to region. This variation is driven by the uneven distribution of solar heating, the individual responses of the atmosphere, oceans and land surface, the interactions be- tween these, and the physical characteristics of the regions.
How do temperatures in different regions vary?
There are differences in climate around the world because of differing amounts of radiation received from the Sun at different parts of the Earth at different times of the year. More heat from the Sun is received near the equator than near the north and south poles where the angle of the Sun’s rays is lower.
Are localized climates that differ from the main regional climate?
A localized climate that differs from the main regional climate is called a microclimate. If you climb to the top of a mountain, you can experience a type of microclimate; the climate becomes cooler with increasing elevation.
