How is the Heat Index temperature different from the air temperature?

The first quantity is known by several names. Depending on what station or
channel you listen to or watch for your weather information, you'll hear about
the "heat index", "temperatiure-humidity index", "discomfort index", "real-feel
temperature", and maybe some others. It's a number derived from a combination
of the air temperature, humidity, and wind, to come up with a temperature in
cool dry air where humans would feel equally comfortable.
Humidity and wind have an effect on our comfort, because they affect the rate
at which moisture evaporates from our skin, taking heat with it. Humidity in the
air reduces the rate at which we can dissipate body heat, so it makes us feel warmer.
Wind increases the rate of evaporation, so it makes us feel cooler.

The temperature of the air falls at night because the earth loses heat by?

When a volume of air is compressed what happens to its temperature?
Obviously the temperature of air will increase. Because when you compress the air you are doing some work on the air which in turn is converted into heat and thus increase the temperature of compressed air
Why do they measure temperature in the shade?
Direct sunlight would heat the thermometer higher than the actual air temperature. A reading would be more accurate if taken in the shade, where the temperature reading would not be greatly different.
What is the difference between heat and humidity?
heat refers to the amount of high temperature in air.... and humidity refers to the amount of water in air.....
What is different between cooler and heat exchanger?
Both the cooler and heat exchanger perform the same function as they remove heat from the engine. Two popular types of coolers are air-to-air inter-coolers that allow air to flow over fins and air-to-water models. The heat exchanger is often mounted in front of the radiator and uses airflow to reduce water temperature.
What is the index that combines air temperature and relative humidity to determine an apparent temperature?
Heat Index.
The heat index indicates?
The heat index combines air temperature and relative humidity to determine how hot it feels outside.
Heat index indicates?
The heat index combines air temperature and relative humidity to determine how hot it feels outside.
What is corrected effective temp index?
It is an index of thermal comfort & combines effect of temperature,humidity,velocity of air & mean radiant heat.
What is the Apparent Temperature when the Air Temperature is 80 F and the Relative Humidity is 30 percent?
The heat index can be calculated when the air temperature is greater then 80F and the relative humidity is at least 40%.
How is temperature diffrent from heat?
Heat is the cause and temperature is the effect. Heat is energy but temperature is outcome of storage of such heat energy in a body. If same amount of heat is given to the same mass of water and aluminium, then temperature will be more in aluminium but less in water. This is similar to the collecting air in different containers. Air is equivalent to heat and pressure created is equivalent to temperature.
What is how hot or cold the air is?
I am wondering if you are referring to "heat index" and "wind chill factor". These terms refer to what the temperature actually is and what it feels like.
Taking heat out of the air will do what to the temperature?
Removing heat from the air will lower its temperature.
What is how hot or cold the air feels?
I am wondering if you are referring to "heat index" and "wind chill factor". These terms refer to what the temperature actually is and what it feels like.
Why the temperature of the water at bottom of water fall is different from temperature at the top?
Heat is lost to or gained from the air while falling.
What is meant by the phrase chill factor?
It refers to wind chill factor. This is the decrease in air temperature that someone would feel because of a cold breeze of air flow. The wind chill factor will be lower than the air temperature. The opposite would be used with the heat index.
Why is ocean temperature more constant than air temperature?
The specific heat of water is greater than the specific heat of air.
