Meteoalarm- European Weather Warnings Plus there's a total … National & Regional Forecasts At Clones, a typical inland station the mean diurnal range is 8.4 m/s in January and 6.2 m/s in July. Plus there's a total of the mean number of days yearly with gale gusts.Gales are defined here as winds with speeds greater than 62 KPH (39 MPH or 34 knots). In January the southerly and south-easterly winds are more prominent than in July, which has a high frequency of westerly winds. Weather Extreme Records for Ireland Inhomogenieties arise in wind data time series due to changes in instrumentation and changes in station exposure due to new buildings, tree growth etc. Wind and weather reports & forecasts for kitesurfers, windsurfers, surfers, sailors and paragliders for over 45000 locations worldwide. Weather Observations Website WOW-IE This is a result of surface heating, which increases mixing of the faster-moving air at higher levels with the air near the surface. The prevailing wind direction is between south and west. Weather Extreme Records for Ireland The diurnal variation is much more pronounced in summer than in winter. Each location has an average wind speed for a year in miles per hour (MPH) and kilometres per hour (KPH). During the course of a typical day, the range (difference between the highest and lowest) of mean hourly wind speed is considerable. Wind measuring sites need to be open, level and free from obstructions due to buildings and trees etc., for this reason wind speed and direction are measured generally at 10m above ground level. Peer-reviewed journal articles by Met Éireann staff members Weather radar, wind and waves forecast for kiters, surfers, paragliders, pilots, sailors and anyone else. The UK wind map below shows where will be the windiest places in the UK.
On average there are less than 2 days with gales each year at some inland places like Carlow, but more than 50 a year at northern coastal locations such as Malin Head. Wind is the movement of air caused by pressure differences at the earth’s surface, which in turn are caused by the differential heating of the earth’s surface by the sun. Weather Warnings & Advisories Up until the 1990s, wind speed and direction were measured by Dines pressure tube anemometers, these operate on the basis of the pressure caused by the wind blowing into an opening on the wind facing end of a wind vane, since the early 1990s these have been replaced by cup and vane anemometers, with wind speed measured by rotating cups, and direction by a separate wind vane.The wind at a particular location can be influenced by a number of factors such as obstruction by buildings or trees, the nature of the terrain (roughness) and deflection by nearby mountains or hills. Gust speeds are also recorded, as are the times of highest daily gusts and the mean wind speed and direction at the time of the highest gust and the highest 10 minute mean speed in a 24 hour period. The predicted mean wind speed and power in many such locations is in the range of 8 to 10.5 metres per second which is regarded as sufficient to support economical wind energy projects. Weather Observations Website WOW-IE The tendency for maximum wind speed to occur in the afternoon is noticeable only in the long-term figures and on individual days the maximum may be at any hour. our Climate. Last updated: Fr, 28 Aug, 22:18 BST. Atlantic Charts – 7 day Forecast The diurnal variation is greatest on sunny days and least on dull days. As the effect of surface heating diminishes, the wind speed decreases and during the night there is little variation from hour to hour. At Belmullet, a western coastal station, the mean diurnal range is 11.5 m/s in January and is still as high as 8.4 m/s in July. Worldwide animated weather map, with easy to use layers and precise spot forecast. The method is … Data used in this section have not been homogenised or corrected for roughness.Wind speed and direction are continuously recorded and tabulated, either manually or automatically depending on the station location and type. The wind forecast is available for today and up to five days ahead showing the latest wind speeds and wind gusts.
