A Humidifier
The cold in winter causes the humidity to drop by condensing it out. The heat in summer can cause the humidity to rise by evaporating more water from nearby bodies of water.
The relative humidity decreases. This explains why there is static and people walk around with chapped lips. Here is a link to a good explanation: http://en.allexperts.com/q/Accuweather-2546/2008/6/Physicial-Geography.htm
Ask Dr. Clements...
51%.... open to the Relative Humidity chart in the reference tables. the wet bulb temperature is -1C and the dry bulb temp. is 2C, making a difference of 3C. On RH chart, go down to 3C column (difference between the Wet bulb and dry bulb) until it intersects the dry bulb 2C. At this intersection is 51%
No its the amount of moisture in the air. In effect humidity means it will be hotter with summer type temperatures (because its harder for the sweat galnds to cool yourself because of the film of moisture from humidity) and in winter humidity makes it colder (for same reason, but different effect - its a cold layer sitting on your skin and you feel 'damp'
yeah
It is cold and humid.
The average relative humidity for all of Michigan is in the mid to high 70% range. Flint hangs right around 73%.
It is cold and humid.
The humidity in winter is lower.
The answer depends upon the season of the year. During the winter (dry season) the relative humidity during the day is frequently below 10%. During the summer monsoon the humidity can be 50, 60, 70% or higher. I live in the Chihuahuan Desert and we have had some heavy summer rains in recent days. The last I checked the humidity was 76% at noon.
If you have de-humidifiers then just take out the plug.
You could say "The humidity outside is very high."During the summer the humidity in the air is usually higher than in winter.

Temperature does have a direct effect on relative humidity. ( just to make the water vapor move faster when war and slower when cool). As temperature goes up, the ability of the air to hold more gas goes up, so relative humidity goes down (unless more water vapor is being added). very good answer if you don't trust it. i got an A on a take home test with this answer Temperature affects humidity when they take place in the Dew point when water vapour changes to liquid. At this temperature humidity is high. The higher the temp, the more water vapor can be carried in air. Thus if you heat air (as is done in the winter) the relative humidity drops ... the air seems dryer even though the total amount of water vapor is unchanged.
75 degrees F OK that's fine for temperature but what is the ideal room humidity percentage? Actually, most building codes only require you at keep the temperature at 68 degrees, which is ideal. The ideal room humidity percentage is usually around 50% ASHRAE Standards: 68-74F @40-60% relative humidity in the Winter 73-79F @40-60% relative humidity in the Summer
