FORECAST BUST: WIND SPEED AND DIRECTION
Download scientific diagram | Relationship between wind speed, wind direction and the power output at Sotavento wind farm for three months, January to March . The study focuses on assessing the spatiotemporal relationship between wind speed and direction and noise level and determine the extent. Relationship between wind direction and air temperature in the. Osaka center . Because the wind speed dropped below the 2 m/s, the wind direction during.
On a clear night the opposite is the case. Light winds at night will allow cool air to build at the surface. If winds are stronger than expected then the surface temperature will be warmer since the wind will mix warmer air aloft with the shallow cool air building at the surface.
The wind speed is also important in determining the rate at which thermal advection will take place. Wind direction shifts can dramatically alter the forecast.
It is important for the forecaster to know where significant water bodies are in relation to the forecast area. It is also important to know where significant elevation changes occur in relation to the forecast area.
Some wind directions will bring in more moisture while others will bring in drier air.
Some wind directions will promote upslope flow while others will promote downslope flow. If the wind direction ends up being different than forecasted, certain forecast areas are very likely to have a busted forecast.
Wind Speed and Direction
This is especially true for forecasts made out several days into the future. Earth's Tilt and the Sun Over approximately 40, years, the Earth's axial tilt ranges from As the angle of the Earth in respect to the sun changes, so too does the available energy received from its nuclear furnace. The current axial tilt of roughly As the Earth orbits the sun, the angle of the sun's rays changes across the globe as a direct result of the Earth's axial tilt.
As the rays of electromagnetic energy from the sun enter the Earth's atmosphere, they are either reflected back out to space, absorbed by atmospheric gases or stored in ocean waters or continental surfaces.
The closer the ray's angel of entry is to 90 degrees, the greater the amount of energy that is retained. As a result, latitudes nearer the equator receive more of the sun's energy throughout the year than do higher and lower latitudes.
Wind Belts The equator, at 0 degrees latitude, divides the northeast trade wind zone in the Northern Hemisphere from the southeast trade wind zone in the Southern Hemisphere. In respect to the wind belts, the equator is known as the equatorial doldrums. The horse latitudes are located at 30 degrees north latitude and 30 degrees south latitude, and divide the northeast and southeast trade wind zones from the zones known as the prevailing westerlies.
Above and below the prevailing westerlies at 60 degrees north latitude and 60 degrees south latitude are the polar fronts dividing the prevailing westerlies from the polar easterlies. Sciencing Video Vault Wind Belts and Wind Direction Simply put, the direction of wind flow associated with wind belt zones flows from the direction indicated within its name.
The northeast trade winds flow from northeast to southwest.

The southeast trade winds flow from the southeast to the northwest. The Coriolis Effect If it were not for the Earth's rotation, the winds would simply flow in relatively straight paths from north to south or from south to north respectively. But the Earth does rotate, and as a result the winds are deflected to the right in the northern hemisphere and to the left in the southern hemisphere.
This effect is known as the Coriolis effect and adds greatly to the atmospheric airflow mixture and weather variability.
