What is the purpose of air pressure?
Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather. A barometer measures atmospheric pressure, which is also called barometric pressure.
What are the factors which affect the air pressure at any area?
Factors Affecting Air Pressure:
- Temperature: As the temperature increases, air expands because of which its density decreases which results in low pressure.
- Height from Sea Level:
- Moisture in Air (Humidity):
- Gravitation of Earth:
- Rotation of Earth:
What is the main function of outside air temperature?
Outdoor air temperature is an important factor regarding the building energy balance. Outdoor air temperature affects the heat transfer through external walls and roofs and the heat transfer by ventilation.
What effect does temperature have on air pressure answer?
Whenever the temperature is high, the air pressure is low. As the temperature rises, the air gets heated, expands, and becomes lighter. This lighter air in the vicinity of the earth’s surface starts moving upwards the sky. As a result, the air pressure in such areas decreases.
What is the role of temperature in affecting the distribution of pressure?
Temperature: When the temperature of a place increase, the atmospheric pressure decreases. This is because, increase in temperature results in the heating of the air. Warm air expands. The molecules of the warm air become less dense and hence exert less pressure.
What are the factors that influence the distribution of temperature?
The factors responsible for the uneven horizontal distribution of temperature are:
- Latitude. In the previous article, we have studied that the angle of incidence of sun’s rays goes on decreasing from the equator towards the poles.
- Altitude.
- Land and Sea Contrast.
- Ocean Currents.
- Air Masses.
- Vegetation Cover.
What are the four main factors that influence temperature?
Answer: The factors that affects temperature are altitude, latitude and distance from sea.
What are 6 factors that affect temperature?
LOWER is an acronym for 6 factors that affect climate.
- Latitude. It depends on how close or how far it is to the equator.
- Ocean currents. Certain ocean currents have different temperatures.
- Wind and air masses. Heated ground causes air to rise which results in lower air pressure.
- Elevation.
- Relief.
What are the main influences on mean temperature?
There are several factors that influence the mean temperature. Key factors that influence mean temperature are latitude and altitude or elevation. Land and water heating also makes adifference in the mean temperature as well as cloud cover.
