Cold is the absence of heat, and thus is a product of the removal of the heat. When night falls, we experience the loss of what is called diurnal heating, or heating by the sun. This is caused by the lack of long wave radiation, radiation emitted by the sun directly on the planet, which produces heat as well as the loss of short wave radiation, energy released from the planet which was absorbed as long wave radiation.
It also depends on the season, which is caused by the angle of the Earth in relation to the sun. In the summer, the sun shines directly on the Tropic of Cancer (23 degrees 26'), causing more direct sunlight in the Northern Hemisphere to heat it up. In the winter, the sun shines on the opposite latitude known as the Tropic of Capricorn which causes less heat to generate in the Northern Hemisphere. The angle of the sun directly influences how hot and cold it becomes.
If you refer to a specific area, a city or state as opposed to the country or continent, then you need to look as what are called synoptic scale air masses and semi permanent air masses, which are bubbles of high and low pressure air that influence large regions. For example, in North America, Canada houses the Alberta High Pressure System, which commonly pushes cold air into the continental United States. As winter emerges, this air mass will move into the Central Plains. Smaller systems, known as high or low pressure systems, move throughout the world and affect local temperatures.
The parts of these systems are called the warm front, the cold front and the occlusion. The warm front is a mass of relatively warm air and the cold front is the relatively cold air. As these move over an area they will affect the temperature.
Ask your local weatherman for explanations of what systems are currently affecting your area, as they change daily.

What happens to the vapor in the air when it gets cold?
When the vapor in the air gets cold, it condenses into liquid water droplets. This process is called condensation. This is why you see fog, clouds, or dew forming when the temperature drops and the vapor in the air loses heat energy.
when water vapor gets cold it turns into a?
When water vapor gets cold it condenses into condensation.
How does low and high pressure system tell you differ from what warm and cold fronts tell you?
Low and high pressure systems indicate the atmosphere's vertical movement and general weather conditions, respectively. Warm and cold fronts, on the other hand, denote the boundaries between air masses with differing temperatures and lead to specific weather phenomena, such as precipitation and temperature changes.
Why does the alcohol in a thermometer go down when the weather is cold?
As the atoms lose energy (through the cold weather) they lose energy and vibrate less. If you imagine this, as they vibrate less, they don't bump into each other as much and the spaces between the particles decrease. As the spaces get smaller, the whole liquid gets smaller, causing the liquid to "go down".
Is it cold in the center below the earth's surface?
its hot and the deeper you go the hotter it gets
How does it get so cold in Kansas?
When the temperature goes down in Kansas it gets cold
What is the weatheron the planet Mars?
Weather on mars is mostly cold. In the winter it is -200 degrees at the poles. The air temperature rarely gets above 32 degrees F.
What biological creature gets colder the hotter the temperature gets?
An Exothermic or cold blooded creatures internal temperature fluctuates with it external temperature.
How cold does Vancouver get?
It absolutely depends where in the Metro Vancouver you are. The downtown gets a temperature of -3C at its lowest. The suburbs and the mountain regions get much lower than that.
Where was the coldest temperature recorded in Illinois?
Illinois enjoys extremes of temperature but also has all four season.
What happens to the temperature in the day compared to night?
it gets hot and cold
What is the temperature in day and during the night in arizona?
in the daylight is warm really hot mostly but when it gets darker mostly it gets darkeranwsered by manalaged 9 year 6
What engine oil should be used in an 05 Tahoe?
That depends on the climate and season. Oil gets thick when it gets cold, so some oils are made thinner than others to compensate for the temperature that they tend to be used in.
What gets hotter when it gets colder?
Your body temperature can increase when it's cold as a result of shivering, which generates heat to help maintain your internal temperature.
What is the average temperature in Vancouver British Columbia at the winter?
It gets hot and cold
Why do the water freeze at 32 Fahrenheit?
because it gets very cold at that temperature.
Does a lizard die when the temperature is too cold?
Everything will die if it is too cold. try dipping a lizard in liquid nitrogen. I guess it depends on how cold it gets. All cold blooded animals slow down and stop moving as the temperature drops.
