how does humidity influence air temperature?

the water is a very special substance. it has high specific heat capacity. meaning that water can absorb so much heat compare to other substances. for example ,water is used in cooling system of engine of a vehicle  bcoz it can absorb so much heat energy generates by the engine. humidity represent how much the water molecule in air. so the more humid the air, the cooler the air temperature the water molecules in air absorp the heat from surrounding thus making the air cooler. Get it?

Warm air holds more water vapor than cold air.  That is why a clothes dryer uses heated air to draw the moisture from the clothes.  It is also why when warm moist air meets cold air it results in precipitation.

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.

Mist cooling is simply introducing an atomized spray of water into an airstream to cool the air.   As the water droplets vaporize and dissolve in the air, they remove heat energy from the air, leaving the air slightly cooler.\n\nThese systems are most effective in dry heat climates, where the relative humidity is low.  The water can evaporate much more quickly, removing more heat.\n\nThe lowest temperature that can be conceivably reached (provided that the system were 100% efficient) is the dewpoint temperature, also known as the wet-bulb temperature.  If the air were cooled to this temperature, its relative humidity would be 100% and it would be at maximum moisture saturation.  So, in most cases, these coolers can only reduce temperatures to 60 or 70 degrees under normal conditions, unless you're in a desert or other arid region.\n\nMost mist coolers are smaller, portable systems that use a common fan with several nozzles in front of it that produce a very fine mist spray of water.\n\nSmaller systems are also available for cooling milling work in tooling manufacturing.  These systems typically have an additive in the water supply to reduce the oxidation effects of the water.

Its probably the humidity. I have friends from africa who tell me that when its over 100 degrees you don't even sweat.

It's the actual temperature with humidity, wind chill factor (if applicable), dew point and other conditions taken into consideration. There's actually a mathematical equation to figure it out but it may be hard to find since the calculations are done by computers these days.

you left out a lot of info lmao.\nwhat is the humidity of the air and what presure are you talking about.\nHeat and cold are regulated by the moisture content of the air.

Salt water does not have any specific effect on weather formation. But all sources of water whether it is river, lake, pond, sea or ocean; by evaporation affect humidity and therefore the weather conditions.

Typically between -20 and +10 degrees Celcius (-4 to +50 F). It depends very much on the amount of humidity in the air. If it is very humid you will start see it at higher temperatures than usual. That's because the air can only contain a certain amount of water vapour at a certain temperature and when the amount of water vapour increases that value the water will condense into liquid water and that's what you see when you "see you breath". The temperature you are referring to is called the dew point and can be found in advanced weather forecasts.

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.

The temp drops 5 degrees Fahrenheit for every 1,000 feet-- assuming the air is dry, or 3 degrees F if the air is saturated.  This is called the adiabatic lapse rate--specifically the DRY adiabatic lapse rate, and it (combined with dew point temperatures) determines cloud base heights (ceiling).  This does not take into account extreme convective effects.  This is the "usual" answer.\n\nAn example:  A parcel of air that starts at 70 deg F at ground level will cool to 65 deg F at 1,000 ft. above ground (AGL).  Let's say the dew point (the temperature at which the air is saturated/100% humidity) is 40 degrees, the parcel will rise to 6,000 feet before condensation occurs.  Now the cloud begins to form.  We can say say that this is the height of the cloud base.  At that point, the wet adiabatic rate of 3 degrees per 1,000 ft. takes over.  It's a little more complicated than that in reality, but this is the basic idea.

Heat isn't a problem for computer equipment until it gets above ~160°F. Whether it's turned off or not doesn't make much difference to the silicon. Humidity, on the other hand, can make a mess of a computer quite fast.

Can you be more specific?  The earth's atmosphere has many gases in it, one being oxygen.  Dry air and humid air will have little difference in oxygen levels.  Altitude, however, does affect oxygen.  The higher you are, the less air, and less oxygen.  I hope this helped.

Yes.. It's called heat index..\n--------------------------------------\nThe heat index (HI) or humidex is an index that combines air temperature and relative humidity to determine an apparent temperature — how hot it actually feels. The human body normally cools itself by perspiration, or sweating, in which the water in the sweat evaporates and carries heat away from the body. However, when the relative humidity is high, the evaporation rate of the water is reduced. This means heat is removed from the body at a lower rate, causing it to retain more heat than it would in dry air. Measurements have been taken based on subjective descriptions of how hot subjects feel for a given temperature and humidity, allowing an index to be made which corresponds a temperature and humidity combination to a higher temperature in dry air.\n\nAt high temperatures, the level of relative humidity needed to make the Heat Index higher than the actual temperature is lower than at cooler temperatures. For example, at 80 °F (approximately 27 °C), the heat index will agree with the actual temperature if the relative humidity is 45%, but at 110 °F (roughly 43 °C), any relative-humidity reading above 17% will make the Heat Index higher than 110 °F. Humidity is deemed not to raise the apparent temperature at all if the actual temperature is below approximately 68 °F (20 °C) — essentially the same temperature colder than which wind chill is thought to commence.\n\nAs relative humidity increases, however, first haze and ultimately thicker cloud cover must develop, reducing the amount of direct sunlight reaching the surface; thus there is an inverse relationship between maximum potential temperature and maximum potential relative humidity, therefore making, say, a simultaneous temperature of 120 °F (50 °C) and 90% relative humidity physically impossible. Because of this factor, it is believed that the highest heat-index reading actually attainable anywhere on Earth is approximately 160 °F (70 °C) in the shade that is 172 °F (78 °C) in the sun.\n\nA good example of the difference between heat index and true temperature would be comparing the climates of New Orleans, Louisiana and Bakersfield, California. New Orleans has lower heat temperatures due to being closer to the Gulf of Mexico, yet the city has a higher heat index because it is a humid heat. Likewise, while Bakersfield actually has hotter daytime temperatures, Bakersfield has a dry heat, so it doesn't feel as hot.\n\nSometimes the heat index and the wind chill factor are denoted collectively by the single terms "apparent temperature" or "relative outdoor temperature".\n\nA typical measurement in the United Kingdom in the hottest areas in the hottest type of weather generally has temperatures that can get above about 90 °F (32 °C) in the shade with 50% humidity which on the humidex chart is 104 °F (40 °C) in the shade and 119 °F (48 °C) in the sun. You should note that humidex and heat indexes are taken in the shade and not the sun; so extra care must be taken while in the sun! For the record, temperatures reached 101.3 °F (38.5 °C) in Kent in mid August 2003 which is the national record; assuming that this was 50% humidity; it would have a humidex of 126 °F (52 °C) in the shade and 140 °F (60 °C) in the sun. Of course in such extreme heat, the likelihood is that the humidity fell and the humidex was not quite that high.\n\nWARNING - Add approximately 15 °F (8 °C) to the heat index for measurements in direct sunshine.\n \nEffects of the heat index (shade values)\nFahrenheit Celsius Notes \n80–90 °F 27–32 °C Caution — fatigue is possible with prolonged exposure and activity \n90–105 °F 32–41 °C Extreme caution — sunstroke, heat cramps, and heat exhaustion are possible \n105–130 °F 41–54 °C Danger — sunstroke, heat cramps, and heat exhaustion are likely; heat stroke is possible \nover 130 °F over 54 °C Extreme danger —

It's to do with humidity of the air. If you watch the weather report you may notice that humidity is expressed as a percentage. This is how 'full' the air is with water vapour. If the air is nearly empty (low humidity) then water will evaporate more quickly. If the air is full (high humidity) the water will evaporate more slowly (it may even receive more water from the air!).\n\nHere is the key: hot air can hold MORE water than cold air. So even if say a gallon of water is the most that some amount of air can hold, if you the air up the air will no longer be 'full' (for example it might be only 70% full, hence 70% humidity).\n\nThis is not a complete answer as I do not know everything about it. It's pretty advanced for 5th grade (I learnt about it in the 11th grade!). For more information look up EQUILIBRIUM in chemistry.

Dew point is the temperature at which the moisture in the air would condense. Relative humidity is the relationship between dew point and ambient temperature. If they are the same, relative humidity is 100%.  The answer is b.
