In meteorology wind speed or wind flow speed is a fundamental atmospheric quantity caused by air moving from high to low pressure usually due to changes in temperature.

. Differences in air pressure and the pressure gradient force are caused by the unequal heating of the Earths surface when incoming solar radiation concentrates at the equator. The main factors that affect wind direction and speed are. Wind solar radiation and clouds contribute to the processes that transfer Blank 1 of 2 and Blank 2 of 2 in the atmosphere.

It is produced by the uneven heating of the earths surface by the sun. What type of characteristics would be best used to describe wind. Two qualities are direction and speed.

Air flows from areas of higher pressure to areas of lower pressure. Prevailing winds are dominant winds in a certain area. Perpendicular to the isobars.

These factors working together cause the wind to blow in different directions and at different speeds. Winds can be described by their magnitude and direction. Wind speed kmhr International description.

The ability to produce precipitation _____ and _____. The pressure-gradient force the Coriolis force and friction. However there is no breaking.

For example a southerly wind refers to wind that starts in. This is the force generated due to the differences in horizontal pressure and it operates from the high pressure area to a low pressure area. Wind characteristics pertinent to turbines are wind speed direction and seasonal patterns.

Because of the energy surplus at low latitudes for example the air there is warmer. A light breeze has a force of 2 and wind knots of 4 to 6. 03 Light breeze.

When isobars are close together gradient is steep. Wind can be characterized by its speed and direction. It is also called a weather vane.

This is enough for you to feel the wind on your face and for wind vanes to move. Effect of wind on the Sea. Where rpm is the rotor speed D is the rotor diameter m.

Since the earths surface is made of various land and water formations it absorbs the suns radiation unevenly. One way to measure wind speed is by observing its effects on objects. Wind Speed - The speed of.

On weather maps places of equal air pressure are connected by lines called isobars. D Molecular flux opposite the wind axis divided by the mean molecular number density. Large wavelets to small waves.

Meteorologists use two main measurements to describe wind. For the purposes of formal weather forecasting wind speed is measured using an anemometer see below. The force actually responsible for causing the movement of air though is the pressure gradient force.

Wind direction is where the wind is coming from and wind speed is the measurement of how fast the air is moving. Tools for measuring wind. Since a closely spaced gradient implies a steep pressure change it also indicates a strong wind speed.

Light Wind Small wavelets 3. A wind vane is used to measure direction and an anemometer is used to measure speed. _____ are used to calculate wind speed miles per hour annual deforestation area per year and air pollution.

Meteorologists classify cloud type using the following characteristics. Yield calculations provide a good indication but on-site wind measuring campaigns are essential. Wind speed affects weather forecasting aviation and maritime operations construction projects growth and metabolism rate of many plant species.

Wind speed is defined as the net molecular flux along the wind axis divided by the mean molecular number density. Wind speed is now commonly measured with an anemometer. The winds are represented by the swirling lines.

Flux is the number of molecules crossing a unit area square meter in a unit time second. The wind direction follows the direction of change of pressure ie. For example a southerly wind would blow from the south to the north.

41 Wind speed is considered as crucial parameters for installation of wind energy projects at any location. What term would best be used to describe topographic features in the whole Atlantic Ocean. A very common shape for a wind vane is the shape of an arrow.

Wind has two important characteristicsdirection and speed. US Weather Bureau description. The wind pushes the cups in a circle and the number of turns corresponds to the wind speed.

Magnitude the speed of the wind can be represented by the actual wind speed value typically in knots mph or meters. The direction is often expressed with a reference to where the wind originated. According to Weatherwizkids Wind is air in motion.

The direction of wind can be gauged using an instrument called the wind vane. Every wind vane has two parts the front and the rear. Data analysis reveals that monthly variations in the wind speed at fifteen different sites of the country helps to measure the other wind characteristics such as the modified Weibull scale parameter modified Weibull shape parameters wind power potential and density and capacity.

Wind Direction - Wind direction is described by using the direction that the wind came from. In 1805 a British naval officer named Sir Francis Beaufort developed a wind. For a given wind speed rotor efficiency is a function of the rate at which the rotor turns.

Wind direction is measured a number of ways including weather vanes flags and windsocks. A common way to illustrate rotor efficiency is to present it as a function of the tip-speed-ratio. There is a very light almost quiet rustling of leaves and at this point small wavelets begin to form.
