# Quick Answer: For Which Date And Location Will The Longest Duration Of Insolation Normally Occur?

## What factors affect the duration of insolation?

Solar energy received over the planet’s surface varies according to season, latitude, transparency of the atmosphere, and aspect or ground slope.

Insolation affects temperature.

The more the insolation, the higher the temperature.

In any given day, the strongest insolation is received at noon..

## 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.

## 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.

## What is Earth’s main source of energy?

Solar radiation is the fundamental energy driving our climate system, and nearly all climatic and biologic processes on Earth are dependent on solar input. Energy from the sun is essential for many processes on Earth including warming of the surface, evaporation, photosynthesis and atmospheric circulation.

## Which latitude is the warmest?

When we consider Latitude alone as a control, we know that the low latitudes (say from the Equator to approximately 30 degrees N/S) are the warmest across the year (on an annual basis).

## 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.

## What zone has the lowest insolation?

polar climate zoneThe polar climate zone receives the lowest insolation, as the Earth’s tilt drastically reduces the exposure of the sun to the farthest areas from the…

## Can Net radiation be negative?

Net radiation can be positive, negative, or zero. Net radiation is positive when there is more incoming radiation than outgoing radiation. … At night, net radiation is usually a negative value as there is no incoming solar radiation and net longwave is dominated by the outgoing terrestrial longwave flux.

## At which latitude would the duration of insolation be greatest on December 21?

23.5 degrees S.5. At which latitude would the duration of insolation be greatest on December 21? A 23.5 degrees S.

## Where is insolation the highest?

At the equinoxes, solar insolation is at a maximum at the equator and is zero at the poles. At the summer solstice of the northern hemisphere, daily insolation reaches a maximum at the North Pole because of the 24-hour-long solar day.

## What 3 things happen to insolation?

1. The sun’s angle of insolation is lower at the poles; 2. More light is reflected at the poles because snow and ice is white; 3. The sunlight travels at an angle and so through more distance of atmosphere, so less energy reaches the surface.

## Why is the insolation zero during some hours of the day?

Why is the insolation zero during some hours? There is zero insolation because albedo is so high during those hours. There is zero insolation because it is not hot enough for there to be solar radiation.

## What is the assimilation of insolation by matter?

Absorption is the assimilation of radiation by molecules of a substance and its conversion from one form to another—for example, visible light to infrared radiation (heat).

## What season has the greatest angle of insolation?

On the summer solstice, the Northern Hemisphere has the greatest number of daylight hours, whereas the Southern Hemisphere has the fewest. The angle of the sun above Earth’s Northern Hemisphere is greatest on this day.

## What latitude gets the most direct sun on March 21st?

23.5 degrees north latitudeAfter the vernal equinox, the most direct rays of the sun striking the earth continue to migrate north. On June 21/22, the most direct rays of the sun fall on locations situated at 23.5 degrees north latitude.

## In which month is the duration of insolation the longest?

June 21stThe duration of insolation varies with latitude and the season of the year. Maximum insolation occurs in the Northern Hemisphere around June 21st (Summer Solstice).

## Why dont the dates of the maximum and minimum temperatures coincide with the dates of the maximum and minimum insolation?

Why don’t the warmest and coldest months coincide with the months that receive the maximum and minimum insolation? Because the earth takes time to absorb the visible light from the sun, and it will be warmest a month after the highest insolation and coldest a month after the lowest insolation.

## What time of day does maximum insolation occur?

(sun is at it’s highest point – usually around 12:00 p.m.) The time of the highest temperature lags behind the time when the most intense insolation is occuring. -the average warmest day of the summer occurs in late July, around a month after the longest day of the year.

## Whats the longest day of the year?

June 20The summer solstice happens today, Saturday, June 20, at 4:43 p.m. CDT. That’s when the sun will reach its northernmost point in the sky. It marks the beginning of summer in the Northern Hemisphere and the beginning of winter in the Southern Hemisphere.

## 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.

## What causes the season?

The Short Answer: Earth has seasons because its axis is tilted. Earth’s axis is always pointed in the same direction, so different parts of Earth get the Sun’s direct rays throughout the year.
