Clouds can decrease the range of daily temperatures because ________.
Clouds will either be composed of ice or water droplets depending on the height of the cloud and the temperature of the atmosphere. Because the droplets are so small, they can remain in liquid form in temperatures as low as -30 °C. Extremely high clouds at temperatures below -30 °C are composed of ice crystals.he warmer the air is, the more water vapour it can hold. Clouds are usually produced through condensation-as the air rises, it will cool and reducing the temperature of the air decreases its ability to hold water vapour so that condensation occurs. - Diurnal Temperature Cycle-the repeating pattern of daily temperatures. - Diurnal Temperature Range-the differences between the minimum and maximum temperatures on any given day. - Daily Mean Temperature-averaging the maximum and minimum temperature for a 24 hour period.- Similar temperature cycles also occur on monthly, annual, and interannual time scales. A rising parcel always expands because atmospheric pressure always decreases with altitude and the parcel loses kinetic energy when converting it to potential energy, which also results in a cooling in temperature of the parcel. - **A rising parcel always cools. ** A descending parcel always warms. Also, pollution can decrease the daily temperature range via such clouds: High clouds left after a thunderstorm spread out across the sky and look like anvils. These clouds cool the earth during the day with their shadows but trap heat like a blanket at night.Pollution can cause clouds from late afternoon thunderstorms to last long into the night rather than dissipate, causing warmer nights.hese clouds cool the earth during the day with their shadows but trap heat like a blanket at night.

The diurnal temperature range (DTR) is the difference between the daily maximum and minimum temperature. Changes in DTR have multiple possible causes (cloud cover, urban heat, land use change, aerosols, water vapor and greenhouse gases).Different regions are affected by different factors.last update: 2010/08/31].

The daily range of temperature is the difference between the maximum and minimum temperatures in 24 hours. It has no meaning at latitudes above 66.5 degrees, where the Sun does not appear for 24 hours during the winter solstice.he daily range of temperature is the difference between the maximum and minimum temperatures in 24 hours.

With increases in water vapor, there are associ … ated increases with cloud cover, which in turn increases albedo (reflection). Currently over 28% of the sun's energy is reflected on its way into our atmosphere.16% is absorbed on the way in, most of this by clouds and ozone.ith increases in water vapor, there are associ … ated increases with cloud cover, which in turn increases albedo (reflection). Currently over 28% of the sun's energy is reflected on its way into our atmosphere. Clouds have the opposite effect on temperature at night. More cloud cover than expected at night tends to result in temperatures that are warmer than expected. Less cloud cover than expected at night tends to result is temperatures than are cooler than expected.loud cover has a dramatic effect on the temperature forecast. Clouds can cause the surface temperature to be more or less than expected. If a surface area has an albedo of 10 percent and clouds an albedo of 90 percent then with 70 percent cloudiness the albedo for the area is 0.7(0.9)+0.3(0.1)=0.66=66 percent. This means that 34 percent of the Sun's radiation for the area is not reflected back into space.f a surface area has an albedo of 10 percent and clouds an albedo of 90 percent then with 70 percent cloudiness the albedo for the area is 0.7(0.9)+0.3(0.1)=0.66=66 percent.

Clouds can cause the surface temperature to be more or less than expected. Clouds affect the climate but changes in the climate, in turn, affect the clouds. This relationship creates a complicated system of climate feedbacks, in which clouds modulate Earth's radiation and water balances.1  Clouds cool Earth's surface by reflecting incoming sunlight.louds occur in the lower two atmospheric layers that comprise the troposphere extending from the surface to about 12 km altitude. The uppermost atmospheric layer extends from about 12-100 km and is comprised, going upward, of the stratosphere (containing the ozone layer), the mesosphere and the thermosphere.
