How does solar radiation per unit area vary with latitude?

How does solar radiation per unit area vary with latitude?

The solar radiation per unit of surface area decreases with increasing latitude in each hemisphere, because the greater the latitude, the longer the distance through the atmosphere the Sun’s rays must travel.

How does solar relate to latitude?

The lowest latitudes get the most energy from the sun. The highest latitudes get the least. The tilt of the Earth causes different areas to receive different amounts of solar energy. The difference in solar energy received at different latitudes drives atmospheric circulation.

Does latitude affect Sun’s rays?

Latitude and Temperature At the equator, the Sun’s rays are most direct. This is where temperatures are highest. At higher latitudes, the Sun’s rays are less direct. The farther an area is from the equator, the lower its temperature.

How does incoming solar radiation change with latitude quizlet?

The angle at which the Sun’s rays strike the Earth changes from the equator toward the poles. The result is that incoming solar radiation decreases with latitude. More solar radiation is received in the tropics than at the poles, resulting in an equator-to-pole temperature gradient.

Which latitude receives the greatest amount of solar radiation?

The Equator, at 0° latitude, receives a maximum intensity of the sun’s rays all year.

How does the difference in solar radiation that reaches the lower and upper latitudes explain the way the atmosphere circulates?

Lesson Summary The highest energy UV, UVC and some UVB, gets filtered out of incoming sunlight by ozone. More solar energy reaches the low latitudes and the redistribution of heat by convection drives the planet’s air currents.

How does latitude differ from longitude?

Latitude implies the geographic coordinates that determine the distance of a point, north-south of the equator. Longitude alludes to the geographic coordinate, which identifies the distance of a point, east-west of the Prime Meridian.

How does longitude and latitude affect climate?

Latitude and longitude make up the grid system that helps humans identify absolute, or exact, locations on the Earth’s surface. There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles.

What are two reasons that solar radiation is different at different latitudes quizlet?

How does incoming solar radiation vary with latitude? Why? Depending on the latitude, the intensity of the Sun’s solar intensity is different. For example, at the poles, there is a low angle of solar intensity, and that solar intensity is spread across a wider area.

How does solar radiation vary with latitude as you move away from the equator quizlet?

As we move further away from the equator the Earth surface will tend to have more insulation from the solar radiation due to the tilt of the earth and the angle of the sun. Whereas, places closer to the equator are more exposed to solar radiation.

Which latitude receives the least amount of solar radiation?

Earth receives different amounts of solar energy at different latitudes, with the most at the equator and the least at the poles.

Why does temperature vary with latitude?

Because of spherical shape of the earth, at lower latitude i.e. near equator the solar radiation is more because it receives directly vertical rays so more energy is gained i.e. more hot. So temperature varies according to latitude.

Where does the sun’s radiation reach the Earth?

On the daylight side, only the point directly under the Sun receives full-intensity solar radiation. From the equator to the poles, the Sun’ rays meet Earth at smaller and smaller angles, and the light gets spread over larger and larger surface areas (red lines).

What determines the angle of attack of solar radiation on Earth?

Latitude and time of year determine the “angle of attack” solar radiation makes on the atmosphere. If the sun is directly overhead, then the radiation 1) comes through the thinnest layer of atmosphere, and 2) any given area of the wavefront impinges on the smallest amount of surface.

How is energy from the Sun spread evenly over the Earth?

Energy from sunlight is not spread evenly over Earth. One hemisphere is always dark, receiving no solar radiation at all. On the daylight side, only the point directly under the Sun receives full-intensity solar radiation.

What is net radiation on Earth?

Net radiation is the difference between all incoming radiation and all outgoing radiation. For the entire Earth and atmosphere, the net radiation is zero over a year. We saw earlier that solar energy input varies strongly with latitude. Read everything about it here. Also asked, where is net radiation highest?
