The number of days that the skies are cloudy and the amount of rainfall in the area is one of the main factors in determining areas climate. As for the whole earth, clouds are a main factor in the greenhouse effect. As pointed out above, low-level clouds usually cool the earth with high-level clouds adding to the greenhouse effect with a slightly overall positive feedback to the increasing moisture in the air that we observe because of global warming. There are many types of clouds and each type contributes a different amount to the greenhouse effect, but overall water vapor and clouds account for about 75% of the greenhouse effect and the other gases primarily CO2 account for the that other 25%.
Ok u can forst start off by drscribin the rain cycle and how the clouds are formed. Then move on to discuss the unequal distribution of clouds over the earth and how the temperature and humidity of any place effects the cloud cover. Then talk about the albedo effect as suggested previously and also talk about how the clouds reflect back any harmful rays from the sun. Clouds also absorb any heat from the sun and thus make the clomate cooler. Rainfall is an obvious way in which clouds effect the climate. Thts all i know.... Hope this helps u and good lick with ur speech!!! ????
i try to describe global worming ,actually sun rays touch top of atmosphere 50% due to long distance from sun to earth approx 15%filtered by ozone layer 10% reflect by clouds and dust particles surrounding planet 25%actually reached at earth ,but on earth surface 71%is water a new reflection start again by water and shiny surface like building etc 10%again back but planet clouds and dust particles not allow to go out new direction of sun rays again to earth these rays actually responsible for global worming
Clouds produce both positive and negative feedback for climate. Clouds absorb thermal energy causing a cooling effect. Condensation forces water droplets with the absorbed thermal energy to fall as rain causing a warming on the surface and the air as these droplets evaporate during rainfall they release thermal energy. Clouds prevent thermal surface energy from reflecting back out into space causing a warming effect. Clouds also reflect solar radiation back out into space preventing it from reaching the surface causing a cooling effect.
In essence clouds regulate climate. Global warming causes faster evaporation of water from the oceans and creates more clouds. More clouds reflect more solar radiation back out into space and remove thermal energy from the atmosphere in rain. And prevent thermal energy from escaping back out into space This creates a more seasonally stable climate by limiting the difference in seasonal temperature changes. Global cooling reduces evaporation from the oceans. More solar radiation reaches the surface causing a hotter thermal absorbsion and allows the therml energy to be released back out into space during the nightime. This creates large temerature swings between day and night. Also differences in seasonal climate are vast. Global cooling creates an unstable climate that varies greatly during seasonal changes because of the lack of clouds to regulate it.
These wild hot summers and cold as hell winters are more aligned with global cooling than global warming it one stops to reason.
i need a 3-5 short summary on how clouds effect the earth for i speech today please help
