Information on wind speed and patterns is integral to the fields of renewable energy, climate change, and weather preparedness. Sea heaps up and white foam from breaking waves begins to be blown in streaks along the direction of the wind. Wind Map; Flow Map; Sea Surface Currents. The National Centers for Environmental Prediction (NCEP) and the National Center for Atmospheric Research (NCAR) used a computer model of Earth's atmosphere and a database of atmospheric pressure measurements from around the world to produce a picture of how Earth's atmosphere has moved since 1948. Wind + Gust Map; Nowcast Map; Radar / Precipitation; Satellite / Clouds; Sea Surface Temps; Forecast Map; Onsite Reports Map; NWS Marine Forecasts; Customize (Advanced) Spot Info. Branches of a moderate size move. Maps show the average (mean) wind speed as well as two components of wind direction: U-wind represents the east-west component of wind and V-wind represents the north-south component. This tool shows maps of average monthly wind speed and direction for the contiguous United States from 1950 to the present. These types of instruments are used by the wind energy industry, both for wind resource assessment and turbine control. Leaves rustle. [2] Both of these instruments work by moving to minimize air resistance. Weather radar, wind and waves forecast for kiters, surfers, paragliders, pilots, sailors and anyone else. Being able to quicky convert wind speed values from units like knots, beaufort, m/s and km/h to another is quite helpful when you're in a pinch. You can produce and compare maps of wind patterns across the contiguous United States for any month from 1950 to present. Wind direction is usually reported in cardinal directions or in azimuth degrees. The sea is completely covered with long white patches of foam flying along the direction of the wind. Sea completely white with driving spray; visibility very seriously affected. Cars veer on road. Worldwide animated weather map, with easy to use layers and precise spot forecast. Box 1208 1 Weather Lane Gray, ME 04039 Probably some spray. Considerable and widespread damage to vegetation, a few windows broken, structural damage to mobile homes and poorly constructed sheds and barns. This last technique is often used by golfers because it allows them to gauge the strength of the wind. The way a weather vane is pointed by prevailing winds indicates the direction from which the wind is blowing. Wind direction is determined by the direction from which it originates. METAR, TAF and NOTAMs for any airport in the World. [7] This is accomplished by wetting the finger and pointing it upwards. … The same principle is used to measure the dew point using a sling psychrometer (a more accurate instrument than the human finger). Are you missing any calculations? In addition to our wind speed converter, you can also convert precipitation values and distances (e.g. Easily add multiple stops, live traffic, road conditions, or satellite to your route. [3] The larger opening of a windsock faces the direction that the wind is blowing from; its tail, with the smaller opening, points in the same direction as the wind is blowing. Small trees begin to sway. Large wavelets. Effort needed to walk against the wind. Wind forecasts, wind maps and live weather reports for kite- and windsurfing, sailing and fishing Small branches begin to move. Knowing the difference in atmospheric pressure from one location to another enabled scientists to program the model to compute wind speeds. Wind direction is reported by the direction from which it originates. This dataset is called the NCEP/NCAR Reanalysis. Widespread vegetation damage. Wind Direction Unavailable; Down Station; My Weather. Large waves begin to form; the white foam crests are more extensive everywhere. Official MapQuest website, find driving directions, maps, live traffic updates and road conditions. Severe Alerts Safety & Preparedness Hurricane Central. Severe. Debris may be hurled about. Maps show the average (mean) wind speed as well as two components of wind direction: U-wind represents the east-west component of wind and V-wind represents the north-south component. [4], Modern instruments used to measure wind speed and direction are called anemometers and wind vanes, respectively. Using the wind radar map, you can predict the wind direction and check where the gusty wind is. Users can identify months or trends of unusually high or low wind speeds, or examine the U-wind and V-wind components to look for changes in wind direction. When a high measurement frequency is needed (such as in research applications), wind can be measured by the propagation speed of ultrasound signals or by the effect of ventilation on the resistance of a heated wire. Forecast models ECMWF, GFS, NAM and NEMS [1], A variety of instruments can be used to measure wind direction, such as the windsock and wind vane. Newer digital wind maps present wind speeds using color and wind direction using arrowheads. Large branches in motion. Chance of some spray. Wind direction is measured in degrees clockwise from due north. When you have eliminated the JavaScript , whatever remains must be an empty page. For each month and parameter, the tool shows the climatological mean wind (average over the previous three decades), observed winds, and wind anomaly (how much faster or slower wind blew compared to the long-term average for that month). The wind map is a personal art project, not associated with any company. Whistling heard in overhead wires. [8], Convective available potential energy (CAPE), https://en.wikipedia.org/w/index.php?title=Wind_direction&oldid=983097369, Creative Commons Attribution-ShareAlike License, This page was last edited on 12 October 2020, at 06:40. For example, a northerly wind blows from the north to the south. Exceptionally high waves (small and medium-size ships might disappear behind the waves). [1] Wind direction is usually reported in cardinal (or compass) direction, or in degrees. Dense streaks of foam along the direction of the wind. Very high waves with long over-hanging crests. Video & Photos. SYNOP codes from weather stations and buoys. The Current Wind map shows the current wind speed and direction for the most recent hour. The Current Wind map shows the current wind speed and direction for the most recent hour. Consequently, a wind blowing from the north has a wind direction referred to as 0° (360°); a wind blowing from the east has a wind direction referred to as 90°, etc. Weather forecasts typically give the direction of the wind along with its speed, for example a "northerly wind at 15 km/h" is a wind blowing from the north at a speed of 15 km/h. The resulting foam, in great patches, is blown in dense white streaks along the direction of the wind. Do you have feedback? Spray may affect visibility. Small waves, becoming larger; fairly frequent white horses. Twigs broken from trees. Umbrella use becomes difficult. The foam is blown in well-marked streaks along the direction of the wind. Moderate waves, taking a more pronounced long form; many white horses are formed. US Dept of Commerce National Oceanic and Atmospheric Administration National Weather Service Gray - Portland, ME P.O. Updated every three hours. Within the tool, click the Overview link in the upper right for information about the maps. For example, a north or northerly wind blows from the north to the south. On the whole the surface of the sea takes on a white appearance. More damage to most roofing surfaces, asphalt tiles that have curled up and/or fractured due to age may break away completely. Crests begin to break. Step by step directions for your drive or walk. Visibility affected. In addition to our wind speed converter, you can also convert precipitation values and distances (e.g. Technical information specific to this dataset. Send your suggestions, Wind direction rose (cardinals and degrees). Current weather observations and forecast. For your convenience, tables for conversion and wind speed impact on land and sea are provided for you to download as well. Perhaps scattered white horses. In situations where modern instruments are not available, an index finger can be used to test the direction of wind. Enable JavaScript to see Google Maps. Are you missing any calculations? Explore! The air is filled with foam and spray. Wind direction is reported by the direction from which it originates. Providing near real time weather maps of wind strength and direction across the United States In a more detailed weather report, wind direction and speed are shown using a symbol called a wind barb. Everywhere the edges of the wave crests are blown into froth. Whole trees in motion. Wind speed and wind direction. 100 km - < 250 km or approximately 1 degree - < 2.5 degrees, Select variables from pull-down menus to generate maps, ftp site for downloading U and V wind component data. Enter value in any field, the converted values will be calculated automatically. Crests of waves begin to topple, tumble and roll over. Find nearby businesses, restaurants and hotels.
