The Four Forces That Influence Wind Speed & Wind Direction
- Temperature. Air temperature varies between day and night and from season to season due to changes in the heating Earth’s atmosphere.
- Air Pressure.
- Centripetal Acceleration.
- Earth’s Rotation.
What determines wind speed?
In general, the speed of wind is determined by the magnitude of the air pressure difference between two points, with greater speeds resulting from greater air pressure differences. Wind direction results from the orientation of those air pressure differences, with air moving from higher to lower air pressure.
Which factors in wind speed and humidity?
Surface Area and Temperature Temperature and the surface area of the water also influence the effects of wind speed and relative humidity. Water molecules are more exposed to air and more influenced by wind speed and relative humidity, the more a body of water is spread out.
What are the 5 main factors that determine the state and condition of the atmosphere and therefore the weather?
These elements are solar radiation, temperature, humidity, precipitation (type, frequency, and amount), atmospheric pressure, and wind (speed and direction). Learn more about what distinguishes weather from climate.
What two factors determine the wind?
Two factors are necessary to specify wind: speed and direction. What causes the wind to blow? As the sun warms the Earth’s surface, the atmosphere warms too.
Does humidity affect wind speed?
Figure 3 show that higher wind speeds are associated with lower humidity values and lower wind speeds are associated with higher humidity values.
What physical factors cause wind?
The two main factors affecting wind patterns are 1) the heat distribution between the earth’s equator and poles, and 2) the constant rotation of the planet. The sun is Earth’s primary energy source.
Does temperature affect wind speed?
Temperature differences between air masses lead to pressure differences, and this produces wind. The winter brings higher temperature gradients, especially when cold fronts move in from polar regions, and this causes wind speeds that are higher than normal.
What determines the temperature and humidity of an air mass?
Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the the underlying surface properties where they originate. Once formed, air masses migrate within the general circulation.
What factors determine weather?
The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area’s elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and …
What are the four factors that determine weather?
Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth’s tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water.
How does wind speed affect air temperature?
As the wind increases, it draws heat from the body, driving down skin temperature and eventually the internal body temperature. Therefore, the wind makes it FEEL much colder. If the temperature is 0°F and the wind is blowing at 15 mph, the wind chill is -19°F.
What are the factors that determine weather?
The third factor that can determine the weather is if a place is experiencing humidity. Humidity is a measure of the water content of the air mass. The amount of moisture in the air can vary widely depending on the conditions. In the winter, air is generally cooler and drier, whereas in the summer when air is warmer, it can hold more moisture.
How does the rotation of the Earth affect wind direction?
The rotation of the Earth plus differentials in barometric pressure across large-scale areas determine wind speed and direction. The Earth’s rotation causes air from high pressure regions to spiral in to try and equalize the pressure in regions with a low barometric pressure.
What are the driving forces of weather?
The movement of air (wind) is one of the main driving forces of weather. The majority of major and even extreme weather events like cold & warm fronts, clouds, thunderstorms, and hurricanes are all driven by wind. What Is Wind? Wind is the large-scale movement of air from an area of high to an area of low pressure in the atmosphere.
What instruments are used to measure wind speed?
The anemometer is the instrument used to measure wind speed. Consisting of 3-4 half-cups on arms rotating around a central axis, you can typically find it on top of a weather station or at an elevated position. A wind vane (or weather vane) is the instrument used to measure wind direction.
