Evaporative Cooling- The faster molecules escape and become a gas and the slower/cooler molecules left behind, causing a cooling effect.…
At midnight in the shallow layer of the air near the ground, the air temperature is 44°F and the dew point temperature is 36°F. If the air cools at a rate of 2°F per hour until the dew point is reached, and at a rate of 1°F per hour thereafter, then at 6:00am:…
* Cold front- the boundary where a mass of cold air displaces a mass of warmer air.…
The opposite occurs during land breeze. At night, the land cools faster than the water that has absorbed heat from the sun all day. The shallow thermal high forms over land while the shallow thermal low forms over the water. Again, the high pressure flows toward the low which results in a land breeze flowing from land out to sea.…
If a person is exposed to the cold for a prolonged period of a time and their bodily mechanisms are unable to replenish the heat which is being lost, the body’s core temperature will fall prompting characteristic symptoms such as shivering, mental confusion etc.…
Then that "new" air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean 's heat and water evaporating from the surface.…
10. a. Two mechanisms the body uses to cool are dilating blood vessels and skin and making sweat glands produce more cooling sweat.…
1. Describe and give examples of the various ways that heat can be transported in the atmosphere.…
If the ice and water mixture is cooled, the molecules move slower.The slower molecules are more easily captured by the ice, and then freezing rate occurs at a greater rate than…
When it is cold outside and the temperature drops, your body thermo receptors detect the drop and send signals to the hypothalamus. Neurons also send signals to smooth the walls of the blood vessels to make them contract, which creates a narrowing in the blood vessel also known as “vasoconstriction”. What vasoconstriction does is that it slows down and decreases blood flow to your capillaries near the surface and helps your body retain the heat that you do have in order to keep your body warm.…
As the wind increases, the CF increases which gives its stronger wind and greater deflection.…
experiences a drop in temperature. This drop in temperature is caused by the decrease of…

Air becomes cooler when it expands, and warms as it is compressed. Air descending from high altitude warms as it is compressed by the higher atmospheric pressure near Earth’s surface.…
When the ambient temperature is higher than skin temperature, the only effective heat-loss mechanism is sweating. Therefore, any factor that reduces the effectiveness of…
