Question

why is evaporation high at higher latitude ???

Answer 1

Explanation:

15-Nov-2003 — In the presence of ocean heat transport, advection of moisture in the atmospheric boundary layer from the subtropics to the equator also increases the evaporation under the trade winds, but this has a much smaller effect than the wind speed or the cloud–radiation interactions.

Answer 2

Explanation:

1. We sweat in order to cool our bodies. Perspiration is essentially evaporation. Water from our body evaporates, taking energy from our body in the process and thus results in the lowering of our body temperature.
2. During the summer, we wear cotton clothes. Cotton, being a good absorber of water allows more sweat to be in contact with the atmosphere, consequently helping in more evaporation. It is for this reason that we feel cooler when we wear cotton clothes.
3. Water is stored in earthen pots to make it cool. The pores of the earthen pot, just like the pores of cotton cloth provide a larger surface area for more evaporation.
4. An air cooler is more effective on hot, dry days. The basic principle behind the working of an air cooler is evaporative cooling. As on a hot, dry day, the temperature is high and humidity is low, the evaporation rate is higher. The water takes energy from the air and gets converted to vapour. This makes the air cooler.
