What Causes Insolation?

What are the characteristics of insolation?

The two main characteristics of insolation are- 1) It is the coming solar energy which is received and interepted by the surface of the earth.

2) only 51% of the insolation of the earth reaches the earth surface and 35% of the rest 49% is reflected back to the space by the atmosphere..

What is meant by insolation?

1 : exposure to the sun’s rays. 2 : sunstroke. 3a : solar radiation that has been received. b : the rate of delivery of direct solar radiation per unit of horizontal surface broadly : that relating to total solar radiation.

What does insolation depend on?

The solar radiation that makes its way through the atmosphere and to the surface is called insolation. The amount of insolation received at the surface depends on 1) the sun angle, 2) day length, 3) ground slope, 4) path length, and 5) the state of the atmosphere.

Where is insolation strongest?

S. The vertical ray.strikes the equator on March 21 and September 22.The intensity of insolation is greatest on the equator. This is because the angle.of the sun is higher, at close to 90.

What are the 6 factors that affect climate?

LOWERN is an acronym for 6 factors that affect climate.Latitude. It depends on how close or how far it is to the equator. … Ocean currents. Certain ocean currents have different temperatures. … Wind and air masses. Heated ground causes air to rise which results in lower air pressure. … Elevation. … Relief. … Nearness to water.

What are the 7 factors that affect climate?

These include latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds. The global climate system and any changes that occur within it also influence local climate.

What are the 5 factors of weather?

The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area’s elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and …

Why is the angle of insolation important?

If the Sun is 45° above the horizon, the incoming insolation strikes the Earth’s surface at an angle. This causes the rays to be spread out over a larger surface area reducing the intensity of the radiation. … As illustrated, the lower Sun angle (45°) causes the radiation to be received over a much larger surface area.

What is angle of insolation?

The angle of insolation is the angle at which the sun’s rays strike a particular location on Earth. When the north end of the Earth’s axis points toward the sun, the Northern Hemisphere experiences summer.

How do you calculate insolation?

Solar insolation (I) can be calculated using the following formula: I = S cosZ. The maximum amount of solar insolation on a surface at a specific tilt angle can be calculated with the knowledge of latitude and the day of the year, based on the equation of the sun’s position in the sky throughout the year.

How does latitude affect insolation?

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). … 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.

What are the four main factors that affect insolation?

Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth’s tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water.

How does insolation affect climate?

It is the amount of incoming solar radiation that is received over a unit area of the earth’s surface. … Insolation affects temperature. The more the insolation, the higher the temperature. In any given day, the strongest insolation is received at noon.
