why should we feel cool under trees, in the afternoon of a summer day? What are the factors for that cooling ?

There are the reason for that-\n1-High transpiration rate renders tree leaves cool.\n2-High moisture niche near trees,evaporation renders cooling effect.\n3-Wind passing through leaves becomes less warmer.\n4-Green plants not only absorb a significant portion of the sunlight to invest as energy in photosynthesis to produce sugar resulting into fall in temperature.

The forest, i like to feel the life around me, the energy of the forest, the fresh air, the nature noise in the wind and the power of the nature

Stay out of direct sunlight when it FEELS hot.\n\nTry to find a breezy place to be in, again, out of the sun.\n\nDrink plenty of cool water, and even splash some on yourself occasionally.\n\nDress in the minimum amount of clothing you are comfortable with, or which is socially appropriate.\n\nWear light colors such as white, yellow, pale green or blue, etc.  No darks such as black, grey, navy blue, etc.\n\nSandals instead of shoes and socks.\n\nStay cool!\nOC

I have to disagree with bobpegoh.  Wind chill DOES change the actual physical temperature of anything that has moisture. Nor is it a matter of simple heat transfer, although that can come into play.\n\nThis is the basic answer to your question - your skin has moisture but the outside of the pipe (where the wind hits) is dry.  If on a windy day you were to put something that absorbs water easily outside, you would feel the item cool in the wind.\n\nThe chilling effect is caused by evaporation (see the link below).  The physics is complicated, but basically when the humidity is below a certain point, water will evaporate and use some of the heat energy in your skin to accomplish that.\n\nPractical exercise.  Take a small wash rag and get it wet, squeezing out excess water.  Swing the rag  in a circle as fast as you can for a minute or so.  When you stop, the rag should be noticeably cooler than when it started.\n\nHow much of the heat energy depends on the relative humidity* - as the humidity gets lower, it takes less energy for the water to evaporate, so it doesn't cool down as much.  When the RH gets higher, evaporation will take more energy until the point where there is too much humidity and the water stops evaporating altogether.\n\nRelative humidity and evaporation are a critical part of our bodies ability to regulat heat.  Our bodies actually generate quite a bit of heat just on normal stuff like breathing and circulating blood, and without a way to cool down, our bodies would overheat.  One way we do this is to take advantage of evaporative cooling by sweating.  Wind increases the cooling and blows warmed, humid air away from our body.  \n\nThis is why weather people talk about "heat index" - when the temperature and  humidity get high, our bodies can't dump the excess heat without help.  The heat index is a comparison of how easily our body can dump heat at the current temperature and humidity vs. the current temperature and a standardized humidity.

Here in Egypt it feels great. No rain and no heat either just some fresh air. Hope you feel it

sundevil is right, it has to do with the ability of matter to conduct heat away from your body. Since your body is always generating heat by cellular respiration (your cells burning food in order to function), your body will increase in temperature if there is nothing to take away the energy, causing you to feel hot. Gases are poor conductors of heat, so they have to be much cooler than you to be effective coolants. Once you transfer some heat to the air near you, that air has to transfer heat to other air near it before it can absorb any more. Gas molecules are far apart and  transfer energy betwen each other much less than solids and liquids. Your body will keep making itself hot faster than the air can cool it down. Liquids and solids have much larger heat capacities, so they can absorb energy without much raising in temperature and are much better conductors of heat, transfering energy to other molecules so they can absorb more.

in winter  the earth is far away from the sun as  compared to summer so we receive less heat and we feel cold in winters

That's not the way it works...in the summer, it's warmer because the earth tilts on it's axis towards the sun...the suns radiation then has a direct 'shot' at us. In the winter the earth tilts away from the sun, and the suns rays have to go through much more of the atmosphere to get to us...\n\nAs for being cooler...I think it has to do with air pressure at higher altitudes, and being further from the heat being reflected off the ground...

Probly Early morning or late after noon. That way there is sunlight (plants need it you know) and its not extreamly hot or cold.

It's cooler in hot weather.

Feels great, especially when there's a nice breeze and I am wearing shorts. Sweet!

i like spring best cause in the winter it's too cold, in fall i have to rake leaves and bag them, and in the summer it's too hot. in spring, the air smells fresh after rain, and the grass turns green, and the trees grow leaves.

I LIKE IT WHEN IT FEELS A LITTLE LIKE SUMMER, BUT A LITTLE LIKE SPRING-I LIKE WHEN IT IS ABOUT 78-80, BUT WITH A COOL BREEZE. BUT I HATE HATE HATE HATE WINTER-SO BORINGGGGGGGGGG

On body regulates it's heat through persperation.  It's not as much the temperature that makes it feel hot as the humidity.  The higher the humidity the less moisture evaporated from the skin thus reducing the cooling effect.

the Sun,and the earths Bio-mass.\nthe sun makes it hot (you may know that already)\nand the trees(bio-mass) absorb heat and release it .\nso regulating temperatures between day and night.\nthe ozone layer and aquifiris manta(atmosphere ,clouds,mist etc.)\nworks as a filter and determines how much sun(heat)is allowed to enter.

Forest and the trees perform a lot of functions to receive more rains. There is always evaporation of water vapour from the leaves which will become clouds and then precipitate into rain during the night or at cool climate.  The climate becomes almost cool during night time and cause the rain.  All passing clouds are interrupted by the tall trees and cause rainfall because of the cool climate there.\nThe humidity in the air in forest areas also cause more clouds and also cool climate.  It is almost cyclical. The soil becomes more fertile because of the leaves, animals and insects and helps more plants.
