because night clouds prevent heat from escaping through the atmosphere and into space.And this process called radiational cooling

Why are some days cloudless?

Cloudless days occur when there is little to no moisture in the atmosphere to form clouds. This can happen when high pressure systems are in control of the weather, creating stable and dry conditions that prevent cloud formation. Additionally, local geography and wind patterns can also play a role in having cloudless days.


Which country has the most cloudy days?

In England Around February,March time you get a few cloudy days. The Humidity in the air is watervapor which is a gas and is invisible.


Will solar panels work on cloudy days?

As long as there is sunlight on the panels, the system will produce electricity. However, production will be less on cloudy days than on bright sunny days. Think of it in terms of visibility. There is still outdoor visibility on cloudy or rainy days, albeit less visibility. There is still production on cloudy days, albeit less production. Since there is no sunlight at night, there is no production at night.


How can thick clouds keep us colder in the day and warmer at night?

Thick clouds can keep us colder during the day by reflecting sunlight back into space, reducing the amount of solar radiation that reaches the Earth's surface. This phenomenon, known as cloud albedo, limits warming. At night, however, clouds act as a blanket, trapping heat that would otherwise escape back into the atmosphere, thereby keeping surface temperatures warmer. This dual effect results in cooler days and milder nights in cloudy conditions.

Why is the temperature during daytime lower on cloudy days than on cloudless days?

Because the clouds block the sun's heat. The clouds pile up on each other and make a some what strong shield against the sun's rays. As for cloudless days, the sun rays hits the Earth, nothing blocking there way. :( i hate cloudless days XD

Records on the cloud cover have been kept in Raleigh North Carolina for 47 years the mean for cloudless days in October is 13 how many cloudless days occurred in October during those 47 years?

To calculate the number of cloudless days that occurred in October over the 47-year period, we would multiply the average of 13 cloudless days by the number of years. This would give us: 13 cloudless days/year * 47 years = 611 cloudless days over the 47-year period in Raleigh, North Carolina.

Why are cloudy days cooler but cloudy nights warmer than the clear ones?

During a clear night, as heat absorbed by the earth during the day seeps out, the atmosphere allows the heat to pass through. During a cloudy night, however, the clouds catch and retain the heat in the atmosphere.Clouds trap heat being reflected from the earthThe heat radiation lost from the earth gets reflected by the clouds back to the earth, warming it. Whereas on a clear night it just escapes into space.


Why are nights cooler and days warmer?

Nights are cooler because the sun is not shining, so there is no direct heat to warm the air. During the day, sunlight warms the Earth's surface, which then radiates heat into the atmosphere, leading to warmer temperatures.

Why we feel warm in cloudy days?

The cloud cover acts like a blanket and traps any daylight warmth rising from the earth. A cloudless night sky allows all the warmth to escape into the atmosphere, resulting in a cold or frosty night.


How many cloudy days were there in seattle in 2008?

Why is the daily temperature range greater on clear days than cloudy days?

Clouds act like a blanket, blocking some incoming and outgoing heat. So a desert, which is usually cloudless, can be very hot during the day, but very cold at night, when all the heat escapes into space.
