Knowing the direction of the wind is an important part of predicting weather because wind brings us our weather. The arrow will point to the direction the wind is blowing from so if it is pointing to the east, it means the wind is coming from the east. Additionally, wind direction is where the wind is blowing from.
The speed is determined by the rate of air pressure change, or gradient, between the two pressure areas. The greater the pressure difference, the faster the winds. The wind is caused by differences in atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.
This happens because the moving mass of cold air is at a much lower temperature than the air being displaced. Temperature gradients are higher during winter as a result, and this brings faster wind. On a windy, chilly day the air temperature stays the same even though you may feel colder when the wind is blowing. When it is windy that warm layer is blown away faster and the stronger the wind the faster that layer gets replaced with the cold air. It can certainly feel colder when the wind is blowing.
Wind helps remove the warm air immediately next to the skin and this causes a feeling of it being colder. The wind chill was developed because of the feeling that it gets colder when the wind is stronger due to a more rapid heat loss from the body. The wind speed tends to decrease after sunset because at night the surface of the Earth cools much more rapidly than does the air above the surface. These gusty surface winds usually begin in the late morning hours, peak in the afternoon, and end by early evening.
Winds in the low-levels become much more uniform at night and in predawn hours. Then we move clockwise:. The bottom line: to read wind direction is not difficult, it is easy and interesting.
It is a very useful skill you may use while doing your favorite sports and outdoor activities. Since Windy. You can find out the current wind direction as well as the wind direction forecast in 35 different ways in the app!
The wind direction in the form of arrows is indicated on the widgets of the spots closest to you, including weather stations. For example, in this screen the wind is blowing from the north according to the weather station Ballabio in Lombardy, Italy, and from the east-northeast ENE on the spot Nago-Torbole , Italy:.
When you go to a particular spot screen, you see the wind rose — the one mentioned above. But in Windy. For example, on this screen on spot sailing marina Alesund in Norway, the wind is blowing from west-northwest WNW :.
Learn more about how to read the wind rose in Windy. Scroll down the screen to see wind direction forecast for the next hours during the day and for the next days. First of all, on the Wind and precipitation map, you can estimate the direction visually. And it is very convenient and useful for a general understanding of wind direction in the region:. Then, by clicking on a particular spot or any point on the map, you will see the wind direction information for this spot or a point.
For example, on the same Alesund sailing spot marina in Norway, the wind is blowing from the north-northwest NNW. But in this case, you do not need to read the arrow — the wind direction is written in letters "NNW":. At the same time this wind speed and direction map in Windy. Read the complete guide to the Wind map in Windy.
On the meteorological maps, it is common to use wind barbs to show the wind speed and direction at the same time.
Here, the wind direction is the position of the barb line and feather s in degrees. In other words, the wind blows from the feather s to the opposite direction — often dots. Activate the Wind barbs feature on the wind direction map by clicking on the special icon:. Yes, reading barbs are a bit more difficult than arrows, so learn more about how to read wind barbs. You can also determine wind direction by using isobars.
These are lines on a map that connect points with the same atmospheric pressure. The wind moves counterclockwise around the low-pressure area L and clockwise around the high-pressure area H. This means that the wind will move left or right along the length of the isobar depending on the location of the high or low-pressure areas. Activate the Isobars feature to see how the wind blows in your region and learn more about how to read isobars in Windy.
The cantonment was split into two sections by an irregular ravine, or nullah, running east and west. But you are mistaken in thinking the force west consists of the entire Merrill Horse.
