What is the relationship between sun angle and latitude?
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 is the relationship between latitude and the number of hours of daylight on the equinoxes?
Therefore, on the equinox and for several days before and after the equinox, the length of day will range from about 12 hours and six and one-half minutes at the equator, to 12 hours and 8 minutes at 30 degrees latitude, to 12 hours and 16 minutes at 60 degrees latitude.
What is the relationship between the angle of incidence and the amount of solar radiation at the surface of the earth?
The intensity of solar radiation is largely a function of the angle of incidence, the angle at which the Sun’s rays strike the Earth’s surface. If the Sun is positioned directly overhead or 90° from the horizon, the incoming insolation strikes the surface of the Earth at right angles and is most intense.
How is the summer solstice angle calculated?
To calculate the altitude of the sun at noon of the summer solstice, add the tilt of the Earth, 23.5 degrees, to the 54 degrees to get the angle of 77.5 degrees.
What is the angular relationship between the Subsolar point and the circle of illumination?
What is the angular relationship between the circle of illumination and the subsolar point? Does the angle vary through the year? No, the subsolar point is always at the circle of illumination at 90 degrees.
How does latitude and longitude affect sunrise and sunset?
As latitude increases, sunrises occur later. The pattern of the chart shows that as one goes north, the delay become greater and greater. For example, the difference between 30¡ and 40¡ is about 7¡ longitude. The difference between 40¡ and 50¡ is about 9¡ longitude.
How does latitude affect the number of daylight hours?
The tilt of the Earth’s axis also defines the length of daylight. Daylight hours are shortest in each hemisphere’s winter. Between summer and winter solstice, the number of daylight hours decreases, and the rate of decrease is larger the higher the latitude. The fewer sunlight hours the colder the nights.
What is the relationship between the angle of the noon Sun and the intensity of solar radiation?
What is the relation between the angle of the noon sun and the quantity of solar radiation received per square centimeter at the outer edge of the atmosphere? There is always the same amount of solar radiation. However, the greater the angle the more dissipated the radiation is over the Earth’s surface.
What happens to the air mass as the angle between the direction of the sun’s rays and the surface of the Earth elevation angle decreases?
At higher altitudes Conversely, the absolute air mass, equal to the relative air mass multiplied by the local atmospheric pressure and divided by the standard (sea-level) pressure, decreases with elevation above sea level.
What determines change of seasons?
Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the Northern Hemisphere.
