Clouds form throughout all the levels of the atmosphere and affect both weather and climate. The type and amount of clouds that commonly form over a region impact the precipitation conditions. Cloud cover may also influence temperatures at the surface of the planet.
What causes cloud cover?
Clouds warm and dry Earth’s atmosphere and supply water to the surface by forming precipitation. Clouds are themselves created by the motions of the atmosphere that are caused by the warming or cooling of radiation and precipitation.
Are clouds part of the climate?
Clouds form when water condenses in the sky. The condensation lets us see the water vapor. There are many different types of clouds. Clouds are an important part of Earth’s weather and climate.
How can clouds influence weather and climate?
Clouds can block light and heat from the Sun, making Earth’s temperature cooler. … Clouds within a mile or so of Earth’s surface tend to cool more than they warm. These low, thicker clouds mostly reflect the Sun’s heat. This cools Earth’s surface.
How is cloud cover responsible for affecting weather condition?
Answer: Clouds affect the climate but changes in the climate, in turn, affect the clouds. … Clouds warm or cool Earth’s atmosphere by absorbing heat emitted from the surface and radiating it to space. Clouds warm and dry Earth’s atmosphere and supply water to the surface by forming precipitation.
What does cloud cover mean in weather?
Cloud cover (also known as cloudiness, cloudage, or cloud amount) refers to the fraction of the sky obscured by clouds when observed from a particular location. … The cloud cover is correlated to the sunshine duration as the least cloudy locales are the sunniest ones while the cloudiest areas are the least sunny places.
How is weather different from climate?
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
How is cloud cover shown on a weather map?
The cloud cover in the sky is expressed in eighths of the total sky or oktas, which are shown in weather maps as discs shaded in different proportions.
How cold is a cloud?
the cloud temperature at cloud top ranging from 150 to 340 K. the cloud pressure at top 1013 – 100 hPa. the cloud height, measured above sea level, ranging from 0 to 20 km. the cloud IR emissivity, with values between 0 and 1, with a global average around 0.7.
What weather is associated with the different types of clouds?
- Cumulus – known as fair-weather clouds because they usually indicate fair, dry conditions. …
- Cumulonimbus clouds – thunder clouds that have built up from cumulus clouds. …
- Stratus – dull greyish clouds that stretch across and block the sky. …
- Stratocumulus – low, puffy and grey, forming rows in the sky.
How do clouds help predict the weather?
Here are some hints for predicting weather by reading clouds. Isolated, wispy, or very high clouds are an indication of fair weather. Crowded, dense, dark, and towering clouds indicate changing or worsening weather. … If cloud color, shape, and size change, so will the weather.
Do altostratus clouds rain?
Altostratus clouds are “strato” type clouds (see below) that possess a flat and uniform type texture in the mid levels. … However, altostratus clouds themselves do not produce significant precipitation at the surface, although sprinkles or occasionally light showers may occur from a thick alto- stratus deck.
How does cloud cover influence the maximum temperature on an overcast day?
How can cloud cover influence the maximum temperature on an overcast day? … clouds reflect a significant amount of sunlight that strikes back into space, so that they can reduce the amount of incoming solar radiation, and the maximum day time temperatures.
