June 21st=highest angle of insolation=highest solar intensity=longest path of sun=sun directly overhead at 23.5 North of equator. December 21st=lowest angle of insolation=lowest solar intensity=shortest path of sun=sun directly overhead at 23.5 South of equator.

What season has the greatest angle of insolation?
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. At the winter solstice, the sun does not rise above the horizon north of about 66.5°, where solar insolation is zero.
Where is the angle of insolation the greatest?
The intensity of insolation is greatest at the equator, since it always gets direct (90º) rays of sunlight.
Why is insolation higher in December than June?
The December solstice is when the Southern Hemisphere receives the maximum intensity of the sun’s rays. The angle of sunlight is greater in the Southern Hemisphere during the winter. During the June solstice, the opposite is true.
At what time of day is insolation greatest?
noon
It depends on the Sun’s path. Near noon, the Sun is high above the horizon—the Sun’s angle is greater, and so insolation is higher.
Where is the greatest amount of insolation received quizlet?
–Equatorial regions: The most insolation received. -Mid-latitude regions: A moderate amount of insolation received. Polar regions: The least amount of insolation received.
What season has the least angle of insolation?
Minimum values of insolation are received during the December solstice when day length and angle of incidence are at their minimum (see Table 6h-2 and section 6h). During the December solstice day length is only 5 hours and 33 minutes and the angle of the Sun reaches a lowest value of 6.5 degrees above the horizon.
Why is the insolation for January and July nearly opposite of each other?
The Earth is closest to the Sun on or about January 1, and farthest away on or about July 1 each year. The reason for the seasons lies in the amount of the Sun’s radiation that reaches the Earth. The amount of energy put out by the Sun is a constant.
What is the angle of insolation?
The angle of insolation is the angle at which the sun’s rays strike a particular location on Earth. As Earth orbits around the sun, it travels in an oblong path rather than a perfect circle, so the planet is closer to the sun at some times during the year compared to others.
How do you find the angle of insolation?
The solar declination angle varies from + 23.5 deg on summer solstice to -23.5 deg on winter solstice, and 0 deg on the vernal equinox and autumnal equinox. Solar insolation (I) can be calculated using the following formula: I = S cosZ.
What happens to the angle of insolation on June 21?
June 21st=highest angle of insolation=highest solar intensity=longest path of sun=sun directly overhead at 23.5 North of equator.
Does the angle of insolation change throughout the year?
Sun Angle and Insolation
The amount and intensity of solar radiation reaching the Earth is affected by the tilt of the Earth’s axis and its orientation as it revolves around the Sun. The sun angle at a place varies over the course of the year as a result of the constant tilt and parallelism of the earth’s axis.
Why is less insolation received at the equator in June than in March or September?
Why is less insolation received at the equator in June than in March or September? The daylight period is longest at the equator in June. Winds blow insolation away from the equator in June.
For which date and location will the longest duration of insolation normally occur?
Maximum insolation occurs in the Northern Hemisphere around June 21st (Summer Solstice).
Which part of the Earth receive the highest amount of insulation?
Note: Maximum insolation is received over the subtropical desert, where the cloudiness is the least. The equator receives comparatively less insolation than the tropics.
What is the angle of winter?
At the winter solstice, you subtract the tilt of the earth, so for us the sun angle at the winter solstice is 29.7 degrees.
What climate receives the lowest insolation?
Answer and Explanation:
The 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…
Why is the annual insolation received by the Earth on 3rd January is slightly more than the amount received on 4th July?
On 3rd January, the earth is the nearest to the sun (147 million km). This position is called perihelion. Therefore, the annual insolation received by the earth on 3rd January is slightly more than the amount received on 4th July.
What affects angle of insolation?
The angle of sunlight when it strikes Earth’s surface—called the angle of incidence—makes a big difference. The amount of insolation varies depending on latitude, the time of day, the time of year, and atmospheric conditions. Think about how a beam of light from a flashlight changes depending on its angle.
How and why does insolation change throughout the seasons?
The amount of insolation varies during the year because the Earth is closer to the Sun at certain times of the year , but not the times you would expect — Earth is closer to the Sun during the Northern Hemisphere winter.
What is the angle of sunlight in summer?
During the summer solstice the sun is directly overhead (90degrees) at the Tropic of Cancer and has an angle of 66.5 at the Equator and is at the horizon at the Antarctic Circle (66.5 S).
