Heat can be transferred by three methods.
"Conduction" transfers heat through physical contact. The electric element on the stove heats up, and a pot touching the element also gets hot.
"Convection" transfers heat when a fluid like water or air is heated by conduction, and then the hot fluid travels someplace else and warms something over there. If you have old-fashioned "radiator" heaters in your house or apartment building, a boiler in the basement heats up the water, the water flows through the pipes to the radiator, and the radiator also gets hot.
Once the radiator is hot, it "radiates" the heat energy to you. The energy travels through the air, or through space, at a rate that depends on the differences between the hot item and the cool one.
In weather, we know that a sunny day allows sunshine (also known as "solar heat") to radiate freely from the Sun to the Earth's surface. If it's a clear night, then heat can radiate away into empty space. "Empty space" has no real temperature at all, so the difference in temperature is between a nice day and the absolute zero of outer space, a difference of about 300 degrees.
But if the evening is cloudy, the Earth is still "nice", about 20 degrees C (or about 60 degrees F) and the heat that is radiated from the Earth is radiating to the cloud layer which is probably not much below -10C or 10F, for a difference of only 30-40 degrees; a MUCH lower difference!
So on a clear night, the temperature falls a lot, and falls quickly - even if the day had been quite hot. Desert days can be VERY hot, with temperatures between 35C and 45C, about 95 to 120F. But when the Sun goes down with no clouds, the Earth cools off rapidly, and falls to near freezing.
What else can I help you with?
Is it true that nighttime air temperatures on a cloudy night are lower than they would be on a clear night?
Typically, nighttime air temperatures on a cloudy night are higher than they would be on a clear night. This is because the surface of the earth radiates back heat toward the sky. If the sky is clear, much heat can be lost. However, if it is cloudy, it can keep some of that heat back in. Making the temperatures warmer.
Why is it more likely to be frosty on a clear night than on a cloudy night?
Since clouds are cool moist air, and cold air is heavier than warm air, the cloud cover holds down the warmth that accumulates during the day and keeps the ambient temperature slightly higher over night.
Why does it get hotter at night?
It does not necessarily get hotter at night. The temperature can vary depending on various factors such as cloud cover, humidity, and wind patterns. At night, the lack of sunlight can cause temperatures to drop, but other factors can also influence the temperature.
Why do people often experience feeling hot at night?
People often feel hot at night because their body temperature naturally rises during sleep, their bedding or room temperature may be too warm, or they may be experiencing hormonal changes or illness that can cause night sweats.
What happens to the temperature when clouds are out at night?
The presence of clouds at night can act as a blanket, trapping heat and preventing it from escaping into the atmosphere. This can lead to a milder temperature compared to clear nights when heat escapes more easily.
What is the difference in temperature on a clear night and cloudy night?
On a clear night, temperatures tend to drop more rapidly as heat escapes into the atmosphere. Cloudy nights act as a blanket, trapping some heat and causing temperatures to not drop as much as on clear nights. This can result in warmer temperatures on cloudy nights compared to clear nights.
What is the change in temperature on a clear night with the change in temperature on a cloudy night?
On a clear night, the temperature typically drops more significantly due to the lack of cloud cover, which allows heat to escape into the atmosphere. In contrast, a cloudy night tends to retain heat, as clouds act like a blanket, insulating the surface and preventing rapid cooling. As a result, the temperature change on a clear night is generally greater than on a cloudy night.
What is the name of this type of special light?
On Earth on a clear night the temperature drops more than on a cloudy night why
How would you best describe the general air temperature on a cloudy night?
On a cloudy night, the general air temperature tends to be warmer compared to a clear night. The cloud cover acts as an insulating layer, trapping heat radiating from the Earth's surface. This results in reduced temperature drops during the night, often leading to a more mild and stable atmosphere. Consequently, cloudy nights are typically associated with less temperature variation and a more comfortable feel compared to their clear counterparts.
Why is it clear night is more cooler than a cloudy night?
During a clear night, heat from the surface of the Earth radiates out into space since there are no clouds to trap it. Clouds act as a blanket, trapping heat near the surface and preventing it from escaping, which leads to warmer temperatures on cloudy nights compared to clear nights.
Is it true that nighttime air temperatures on a cloudy night are lower than they would be on a clear night?
Typically, nighttime air temperatures on a cloudy night are higher than they would be on a clear night. This is because the surface of the earth radiates back heat toward the sky. If the sky is clear, much heat can be lost. However, if it is cloudy, it can keep some of that heat back in. Making the temperatures warmer.
What is more likely to be frosty on a clear night than a cloudy night?
On a clear night. Clouds will prevent the heat that the earth has collected during the day because of the sun, to evaporate at night.
Why dews are formed in clear night but not in cloudy night?
Dew forms on clear nights because the ground loses heat through radiation, causing temperatures to drop. As the temperature falls, moisture in the air condenses on surfaces when they cool below the dew point. Conversely, on cloudy nights, clouds act as an insulating layer, trapping heat and preventing the ground from cooling sufficiently for dew to form. This is why dew is more likely to occur on clear nights compared to cloudy ones.
Can one use whereas in a sentence?
On a clear night you can easily study the stars whereas on a cloudy night it is quite difficult.
How is weather on a cloudy night most likely differ from the weather on a clear night?
On a cloudy night, temperatures tend to be warmer due to the cloud cover acting as an insulating layer, reflecting heat back towards the Earth's surface. Additionally, cloud cover can lead to increased humidity and a higher chance of precipitation compared to a clear night, which typically allows for cooler temperatures and drier air. Clear nights often provide better conditions for stargazing, while cloudy nights obscure the night sky.
Why are cloudy night warmer than clear night?
because of the greenhouse effect
Why dew drops are formed rapidly in a clear night than in a cloudy night?
Dew drops form more rapidly on clear nights because the absence of clouds allows for greater heat loss from the Earth's surface through radiation. Without clouds to trap heat, the ground cools quickly, causing the temperature to drop to the dew point, where moisture in the air condenses into droplets. In contrast, cloudy nights retain some of the heat, preventing the surface temperature from dropping sufficiently to facilitate dew formation.
