Why is there a surplus of radiation energy in some parts of the earth and a deficit in others?
At the tropics on the other hand, the dense green vegetation (e.g. the Amazon rainforest) is very dark and absorbs solar energy. The Earth’s tilt (23.5 degrees) creates the seasons, and results in the poles having 24 hr darkness during the winter solstices, whereas the tropics receive insolation throughout the year.
Why do some areas of the Earth receive more energy?
The Sun’s rays strike Earth’s surface most directly at the Equator. Near the poles, the Sun’s rays strike the surface at a slant. The more focused the rays are, the more energy an area receives. The difference in solar energy received at different latitudes drives atmospheric circulation.
Where is there a surplus of energy on earth?
Averaged over the year, there is a net energy surplus at the equator and a net energy deficit at the poles. This equator-versus-pole energy imbalance is the fundamental driver of atmospheric and oceanic circulation.
Why do the tropics receive more solar energy?
Different parts of Earth’s surface receive different amounts of sunlight. The sun’s rays strike Earth’s surface most directly at the equator. This focuses the rays on a small area. Because the rays hit more directly, the area is heated more.
What is the energy balance in relation to the sun and Earth?
The energy balance drives the weather and life on earth. Essentially 100% of the energy that fuels the earth comes from the sun. To maintain a constant global average temperature, all of the sun’s radiation that enters Earth’s atmosphere must eventually be sent back to space.
What part of the Earth do we have surplus and deficit of energy?
You can see in the graph below that there is a surplus of energy between 35˚ North and 35˚ South. In this region, incoming insolation exceeds outgoing radiation. There’s an energy deficit between 35˚ North and the North Pole, and between 35˚ South and the South Pole.
Which part of the Earth have more amount of energy received least amount of energy received?
Earth receives different amounts of solar energy at different latitudes, with the most at the equator and the least at the poles.
Where on earth is there a surplus of thermal energy heat )?
From 0 – 35 ° latitude North and South incoming solar radiation exceeds outgoing terrestrial radiation and a surplus of energy exists. The reverse holds true from 35 – 90° latitude North and South and these regions have a deficit of energy.
