Latitude and Daylight Hours

Asked by: Cortez Herndon

latitude, for example, daylight is 14 hours long in June and 10 hours long in December. At 60° N. latitude, daylight lasts for more than 18 hours in June but for less than 6 hours in December. At the Equator there are always 12 hours of daylight.

How does latitude affect daylight hours?

At latitude 0° (the Equator) day length will be approximately 12 hours. Areas on the Equator have a constant 12 hours of day light all year round. As latitude increases to 80° (polar circles – north or south) day length can be seen to increase to 24 hours or decrease to zero (depending on time of year).

What is the role of latitude in daylight hours and temperature?

Because the angle of radiation varies depending on the latitude, surface temperatures on average are warmer at lower latitudes and cooler at higher latitudes (even though higher latitudes have more hours of daylight during the summer months).

At what latitude do 24 hours of daylight occur?

66.5 degrees latitude

Locations above the Arctic Circle (north of 66.5 degrees latitude; 90 degrees minus the tilt of Earth’s axis) receive 24 hours of sunlight.

Does Sunset change with latitude?

The sunset duration varies by latitude. Farther north or south on the Earth’s globe, the duration of sunset lasts longer. Closer to the equator, the duration is shorter.

Why are days longer in higher latitudes?

In the low latitudes where the Sun’s path is almost vertical the duration of twilight is short. The Sun sinks below the horizon rapidly. In the middle and high latitudes the duration of twilight is long because at these latitudes the Sun has an inclined path.

Does latitude affect sunrise time?

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.

What happens when latitude increases?

As latitude increases, the temperature falls, and vice versa. Generally, around the world, it gets warmer towards the equator and cooler towards the poles. However, other factors could influence the temperature in different locations such as altitude, precipitation, and ocean currents.

Are days shorter at higher latitudes?

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.

Is the sun stronger at higher latitudes?

In general, the sun’s rays are the most intense at the equator and the least intense at the poles. On an average yearly basis, areas north of the Arctic Circle receive only about 40 percent as much solar radiation as equatorial regions.

What latitude is it possible to day without sunrise?

Locations where the Sun remains less than 6 (or 7) degrees below the horizon – between 60° 34′ (or 59° 34′) latitude and the polar circle – experience midnight civil twilight instead of midnight sun, so that daytime activities, such as reading, are still possible without artificial light on a clear night.

Is there always 12 hours of daylight on the equator?

There are always twelve hours of daytime and twelve hours of night-time at the equator, except for two minor effects that increase daytime by about eight minutes.

Does North Pole ever get dark?

The darkest time of year at the North Pole is the Winter Solstice, approximately December 21. There has been no sunlight or even twilight since early October. The darkness lasts until the beginning of dawn in early March.

How many hours of daylight are there at 40 degrees north latitude?

At this latitude the sun is visible for 15 hours, 1 minute and 28 seconds during the summer solstice and 9 hours, 20 minutes during the winter solstice. On 21 June, the maximum altitude of the sun is 73.44 degrees, while it’s 26.56 degrees on 21 December.

How long is daytime at the equator?

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.

Does distance from the equator affect daylight hours?

The distance from the Equator (latitude) determines how unequal the hours of daylight and night are as the seasons change. Areas near the Equator, between the Tropics of Cancer and Capricorn, have little difference in daylight hours between summer and winter. This is why the changes in seasons in the tropics are mild.

How does latitude affect the number of daylight hours a location receives throughout a year?

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 happens when latitude increases?

As latitude increases, the temperature falls, and vice versa. Generally, around the world, it gets warmer towards the equator and cooler towards the poles. However, other factors could influence the temperature in different locations such as altitude, precipitation, and ocean currents.

How many hours of daylight are there at 40 degrees north latitude?

At this latitude the sun is visible for 15 hours, 1 minute and 28 seconds during the summer solstice and 9 hours, 20 minutes during the winter solstice. On 21 June, the maximum altitude of the sun is 73.44 degrees, while it’s 26.56 degrees on 21 December.

How does longitude and latitude affect time?

In theory every 15 degrees change in longitude from line zero in England represents a new time zone or a 1 hour difference. 36024 = 15 degrees. In practice political factors influence where the time zones actually fall.

What latitude is it possible to day without sunrise?

Locations where the Sun remains less than 6 (or 7) degrees below the horizon – between 60° 34′ (or 59° 34′) latitude and the polar circle – experience midnight civil twilight instead of midnight sun, so that daytime activities, such as reading, are still possible without artificial light on a clear night.

Does time depend on latitude?

The time of a place does not depend on its latitude. Time is counted to the east or west of the prime meridian or the zero degrees longitude in Greenwich, England. So the time of a place depends on which longitude it is located.
