On what are weather models based?
The foundation for models are mathematical equations based on physics that characterize how the air moves and heat and moisture are exchanged in the atmosphere. Weather observations (pressure, wind, temperature and moisture) obtained from ground sensors and weather satellites are fed into these equations.
Which factors are important to consider when forecasting weather select three options?
Out of given options clouds , air pressure and temperature are to be consider when forecasting weather. Explanation: Cloud, air pressure and temperature are used for forecasting weather. Clouds are used to determine whether or not there will be rainfall.

Which of the following involves the release of latent heat back into the environment?
Condensation involves the release of latent heat. This is the ‘invisible’ heat which a water droplet ‘stores’ when it changes from a liquid into a vapor. Its subsequent change of form again releases enough latent heat to make the damp parcel of air warmer than the air surrounding it.
How is latent heat transferred to the atmosphere?
In the Earth–atmosphere system, latent heat transfer occurs when water evaporates from a moist land surface or from open water, moving heat from the surface to the atmosphere. That latent heat is later released as sensible heat, often far away, when the water vapor condenses to form water droplets or snow crystals.
What is latent heat and how does it affect the temperature of a substance?
Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
During which phase changes is latent heat taken from the environment?
During a phase change, a substance undergoes transition to a higher energy state when heat is added, or to a lower energy state when heat is removed. Heat is added to a substance during melting and vaporization. Latent heat is released by a substance during condensation and freezing.
Does deposition release latent heat?
The latent heat assoicated with the phase change between solid (ice) and liquid water is 80 calories per gram of water. During the processes of condensation, freezing, and deposition, water releases energy.
Why energy is released during condensation?
Heat is taken from your skin to evaporate the water on your body. Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. An identical amount of calories (about 600 cal/g) is released in this process as was needed in the evaporation process.
What energy is released during condensation?
Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. The latent heat of condensation is defined as the heat released when one mole of the substance condenses.
Is Snow considered condensation?
Other forms of precipitation, such as snow and sleet, are also related to condensation. Snow and sleet are frozen droplets of water.
