why humidity in summer is higher than in winter but it looks quite opposite?

Warm air can hold a lot more water in it than cold air can-just like warm water can dissolve more salt.  Very cold air just cant hold very much water.  In addition, there is a much higher rate of evaporation during warm weather than during cold weather.  However, in tropical climates it is often the case that it is more humid in "winter" because that is the rainy season.

The tilt of the earth on its axis. When it is tiled one way, the sun hits more directly. When it is tilted the other way, it is more spread out.\n\nAgainst what you may think, the earth is actually closer to the sun in the winter than in the summer.

It's probably the humidity level. you "seem" to sweat more when the humidity is high because water cannot evaporate into the atmosphere. when the humidity is low your sweat evaporates quickly, leading you to belive that you didn't work hard enough.

Relative humidity is the amount of water vapor a temperature can hold, Higher temperatures can hold more water vapor.

That is a fantastic question.\nIt is a matter of humidity. The cold weather\nthat allows snow means the air is not humid\nenough to allow an electric current to travel\n(along the water vapor in the air) over the differently\ncharged clouds and sky. People who say temp are\nsort of right, but it is the low temp that leads to the low\nhumidity that causes the "problem".\n\nThanks for asking such a good question.

Hotter air rises when it is hotter than the air around it because it  it is less dense.Vise versa for cold air.

The air mass can hold a maximum of about 6% humidity. This varies with the temperature of the air. The warmer the air, the more water vapor it can hold. The cooler the air, the less vapor it can hold. Relative humidity is a measurement based on the amount of water the air mass, at that specific temperature can hold. For example, if the air mass at a given temperature can potentially hold 4% water vapor, but only has 2% in it then the realtive humidity is 50%. As temperature rises, so does the capability for the air mass to hold more moisture. Assuming no additional moisture is added to the air mass, the relative humidity will decrease as the potential for holding more moisture increases.

Moisture rises in the air as water vapor. When the moisture is rising, the temperature continuously decreases because of atmospheric conditions, and the cooling causes this moisture to "condense" into tiny droplets which are visible yet still light enough to remain airborne.

It's harder for your body to cool off when it's hot because the difference in temperature is not as large as when it is cool.  Put another way, the cool air on a cool day, regardless of the relative humidity, helps to cool you off.

I live in Virginia too.  The answer can be described in two words.  Low dewpoint.  In the summer, you have temps in the 90s and dewpoints in the 70's, making it muggy overnight.  This time of year, the dewpoint is very low, in the 30's and 40's.  The sun is the only thing that holds the temp up.   The humidity is lower in the daytime and higher at night.  It is all about the dewpoint. The higher the dewpoint, the worse it feels to your skin.  The dewpoint can also be too low too.  Making your skin very dry.  I like that because you have a different variety of temps in the same day.  If you like warm weather, go out in the middle of the day. If you like cold weather, go out near dusk.  You have your choice.

the air gets thinner as you rise in elevation.  the thin mountain air doesn't trap the heat as well as the thick air near sea level does.

Because the air closer to the earth isn't always at the correct temperature and humidity level to create clouds.

Sunny days are the result of high pressure systems which tend to be drier and colder in the winter. There is also no cloud cover at night to keep the reradiation in and if there is snow on the ground it is even brighter and the snow is reflecting the heat back out into space.

It depends on where you live. Many parts of the world get lots of rain and clouds in the summertime. \n\nYou may live in a mediterranean climate, where the local weather pattern is rainy winters and dry summers. The reasons for this vary from locale to locale. In the town that I'm writing from, there's a mountain that blocks the cool, moist winds that blow most of the year. We can get a lot of rain coming from the other direction, but the winds only blow that way in wintertime. \n\nTo know exactly why you have those weather conditions, I would need to know where you live.

The higher you go the thinner the air, if there is less air then there is less mass to hold the heat from the sun.

There is a fairly large variation in what people find to be comfortable, from a low of around 65C for those with high metabolisms or mild hyperthyroidism, to 85 or 90 for those with low metabolism.  The variation for humidity is slightly less, from 30-70%, assuming no physiological problems.  Thus, there is a range, just like any other parameter we live with, like the amount of salt in food, or colors on a wall-there isnt any *one* perfect answer.

The air's ability to hold water is a factor of temperature.  That's why humidity is referred to as "Relative Humidity" (its relative to the temperature).  So as the air cools at night, it has less ability to hold water.  What may have been 60% humidity during the day, may end up causing rain during the night.
