The amount of water that actually exists in the air at a given time?
Absolute humidity refers to the amount of water vapor that exists in a given volume of air at a given time. Relative humidity is absolute humidity relative to the maximum humidity for the current temperature.
What do rates of water evaporation depend on?
it depends on the current humidity, if the humidity is high the water will have trouble evaporating because it has no where to go, temperature and atmospheric pressure also play some part.
What controls a tornado?
Tornadoes are influenced by a number of factors withing and surrounding a thunderstorm including various wind current temperature, humidity, and barometric pressure.
How much relative humidity would decrease when temperature rises?
Relative humidity is a ratio between the partial pressure of water vapor and the saturation pressure of water vapor at the current temperature and pressure. If the temperature and pressure change, then the relative humidity will change also. You are correct that higher temperatures allow the atmosphere to hold more water. That means that the saturation pressure of water vapor has increased while the current vapor pressure has remained the same, causing the relative humidity to drop. We think of humidity as how hot and sticky it is outside. The closer the water vapor pressure is to its saturation point, the more hot and sticky we feel. We associate humidity with heat since that is when we are uncomfortable, but rain is caused by the relative humidity rising to 100% because the humid air cooled to the point that the saturation pressure dipped below the current vapor pressure (or other pressure changes, or a combination of both).

If the relative humidity is 90 percent does that mean there is only 10 percent of air left?
No, it means the air can only hold 10% more moisture at the current temperature..
Why do pilots get more accurate readings when they adjust a barometer for the current temperature and and humidity?
the answer is yes
What type of ocean current moves into an area with the result of an increase in the humidity and temperature?
Cold current

What is the average humidity level in Hawaii?
this is the current humidity
What is the current temperature on the Big Island of Hawaii?
The current temperature in Hawaii is 71 Degrees. With a chance of precipitation of 10%. Scattered clouds, with a humidity of 90%. Wind is 5mph, which is normal for this time of year. Current local time is 5am.
What step should you follow to measure humidity with a psychrometer?
A sling psychrometer (or hygrometer) uses the difference in readings between a wet bulb thermometer and another with a dry bulb to measure the relative humidity. The bulb that is wet will cool by evaporation to the "dew point", which is the temperature at which the current humidity would be the maximum possible. Comparing that to the dry bulb (the general air temperature) on a comparative chart will yield the approximate relative humidity.

Why is the dew point never the same?
The dew point is the temperature at which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is a saturation temperature.The dew point is associated with relative humidity. A high relative-humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity will decreaseTherefore, by the above stated reasons (of humidity and barometric pressure and saturation based on temperature) are all reasons the point at wick dew forms is not the same because the regions them selves vary and thus these relative factors maybe dissimilar.
What is the best indicator of current weather?
The best indicator for current weather is a barometer because it tells you if there is rain or if it is sunny.
If the relative humidity is 90 percent does that mean there is only 10 percent of air left?
No, it means the air can only hold 10% more moisture at the current temperature..
