is it poissable for relative humidity to change if the air temperater changed?

Certainly.  RH is the amount of water vapor in the air divided by the maximum amount possible (before condensation occurs) given the temperature.  The maximum possible increases with increasing temperature, so if you heat air in a closed container the RH decreases, and if you cool it enough the RH increases until reaching 100%, when condensation begins.

Water molecules in the air are continually shifting from liquid to vapor. As the Brownian motion and swirling air currents or breezes are moving them around. \n   Thus some of the water at 100 % humidity will be condensing on cooler surfaces while others are evaporating from warmer surfaces eg. your skin.\n   P.S. Your question didn't say but I hope you are standing under a umbrella or something cause at 100% humidity it's likely to be raining. \n\n  Also humidity is relative to air temperature so if the sun is shining during this sun shower, the true quantity of vapor in the air may continue to rise, while humidity actually falls.\n  Nature is truly a conundrum, and even the best super computers, and weather models fail to predict what the weather will do.\n So don't strain your brain.

There are many properties but the two most important are:\n\n1. Temperature (cold or warm air mass) - this affects the density of the air mass as well as it's relative humidity, dew point, how it interacts with other air masses of different temperatures, etc. Temperature is the main driver for what types of weather systems will be generated within an air mass.\n\n2. Absolute humidity - the actual water content of the air mass all attributes to the types of weather systems it will generate, and where highs and lows will form.\n\nAlso, air masses can be moving or stagnant, stable or unstable, constant or dynamic, and I'm probably forgetting others.

How about a small fan with a bowl of water in front of it to increase air humidity.  It may be worth trying...;

barometers only measure atmospheric pressure. The higher the humidity, the lower is the pressure . Of course for a same mass of air, the pressure is directly related to temperature (PV=nRT)\n\nso to answer your question: Lower in the tropical forest

(m)\n\nThe amount of moisture air can retain is determined by its temperature and, to a lesser extent, its pressure. Any sufficient drop in temperature or increase in pressure will cause moisture to condense out of the air. \n\n \n\n Relative humidity is the amount of moisture that is present in the air, compared to the total amount the air could hold at a certain temperature. For example: One cubic foot of air at 80°F, 27°C can hold about 12 grains of moisture.\n\nIf it is holding all 12 grains, it is said to be at 100% relative humidity or saturated. If that same cubic foot of air is holding only 6 grains of moisture, it is at 50% relative humidity.\n  \n Saturation point is the point at which air is holding all the water vapor it can (100% relative humidity). If we added more water vapor to saturated air, the water vapor would condense into a liquid.\n\nRemember that a drop in temperature or increase in pressure will cause moisture to condense out of air that is saturated.\n \n\n  Condensation is the changing of water vapor into a liquid.\n\nDew point is the temperature at which water vapor in the air condenses into a liquid.\n \nPressure dew point is more meaningful because it indicates, at a given pressure, the temperature at which condensate forms in the compressed air lines.

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.

the correct instrument for relative humidity is a hygrometer. a humidifier humidifies the air. a thermometer measures the temperature. a barometer measures the relative air pressure.

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.

Humidity adds to the heat as well as the cold. \nIf the air is saturated with water, and it's also cold outside it will make it so much colder. When it's hot outside and there's high humidity it also makes it hotter, you wouldn't think so, but it feels a lot like a sauna.

Hot air *can* contain more moisture than cold air, but it depends on how much moisture is available for it to contain.

As air gets warmer it's able to contain more water vapor.  An easy way to illustrate this is in a steamy kitchen or bathroom where you'll see that condensation forms on the coldest surfaces such as windows, mirrors, tiles etc.\n\nWhen the amount of water vapor in the air reaches it's maximum point the air is described as being saturated (saturation vapor pressure or SVP for short).  SVP is therefore reached more quickly when the air is cooler.\n\nWhen air reaches SVP it has to deposit the excess moisture which it does as dew or condensation and the point at which this occurs is called the dew point.  The colder the temperature the lower the dew point which helps explains the cool mornings when there's dew on the grass.\n\nHumidity is a measure of the amount of water vapor that's present in the air and is measured as a percentage of the maximum possible.  So a Relative Humidity (or RH) or say 60%, means that the air contains 60% of the maximum possible water vapor.  As mentioned, the amount of water vapor possible increases with temperature and so RH is affected by temperature.  An RH of 80% in a hot tropical climate is going to feel much damper and humid than an RH of 80% in a cooler climate.

A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. This doesn't mean that the relative humidity must be 100 percent in order for it to rain -- it must be 100 percent where the clouds are forming, but the relative humidity near the ground could be much less.\n\nHumans are very sensitive to humidity, as the skin relies on the air to get rid of moisture. The process of sweating is your body's attempt to keep cool and maintain its current temperature. If the air is at 100-percent relative humidity, sweat will not evaporate into the air. As a result, we feel much hotter than the actual temperature when the relative humidity is high. If the relative humidity is low, we can feel much cooler than the actual temperature because our sweat evaporates easily, cooling us off.
