The difference in solar energy received at different latitudes drives atmospheric circulation. Places that get more solar energy have more heat. Places that get less solar energy have less heat. The air above the areas receiving more heat warms up and rises.
How does solar exposure affect temperature?
When the sun’s rays strike Earth’s surface near the equator, the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures.
How does solar radiation affect air temperature?
It is due to the fact that air temperature is directly related to the global solar radiation. So, increase in solar radiation increases the air temperature.
What happens when a hemisphere receives more solar radiation?
The combination of more direct rays of sunlight and more hours of daylight causes the hemisphere tilted toward the sun to receive more solar radiation and to have warmer temperatures. When the Northern Hemisphere is tilted toward the sun, latitudes between the equator and 90°N (the North Pole) are experiencing summer.
How does incoming solar energy affect climate?
The resulting imbalance between incoming solar radiation and outgoing thermal radiation will likely cause Earth to heat up over the next century, accelerating the melting polar ice caps, causing sea levels to rise and increasing the probability of more violent global weather patterns.
What happens to the temperature of the air when altitude increases?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.
How can solar radiation affect the weather?
Researchers have shown that UV radiation affects climate through direct heating and the production and destruction of ozone in the stratosphere, which then leads to regional effects at Earth’s surface through a complex chain of mechanisms.
What happens to solar radiation reaching the top of the atmosphere?
About 29 percent of the solar energy that arrives at the top of the atmosphere is reflected back to space by clouds, atmospheric particles, or bright ground surfaces like sea ice and snow. … Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.
How is radiation affecting the Earth’s temperature?
When visible light and high frequency infrared radiation are absorbed by the surface of the Earth, the planet’s internal energy increases and the surface gets hotter. … Some of this infrared radiation is transmitted through the atmosphere back out into space, and some is absorbed by greenhouse gases in the atmosphere.
How does the amount of solar radiation affect temperature at different heights distances from the surface?
Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures. At higher latitudes, the angle of solar radiation is smaller, causing energy to be spread over a larger area of the surface and cooler temperatures.
Which hemisphere receives more energy?
The Southern Hemisphere receives more energy during December (southern summer) than the Northern Hemisphere does in June (northern summer) because Earth’s orbit is not a perfect circle and Earth is slightly closer to the Sun during that part of its orbit.
Why does the Northern Hemisphere receive more solar energy half the year than it does the other half of the year?
As Earth orbits the Sun, the inclined axis causes the Northern Hemisphere to tilt toward the Sun for half of the year (our spring and summer seasons). During this time, more than half of the Northern Hemisphere is in sunlight at any instant of time.
How does longer daytime affect the amount of solar energy received by the Earth?
When the sun’s rays are vertical, the Earth’s surface gets all the energy possible. The more slanted the sun’s rays are, the longer they travel through the atmosphere, becoming more scattered and diffuse. … When the sun is nearer the Earth, the Earth’s surface receives a little more solar energy.
