Katabatic and Anabatic Winds:
Local Surface winds are sometimes more a function of Temperature Differences between mountain tops and lower elevations than overriding Synoptic winds. These winds are sometimes called Mountain Winds as they occur most frequently in mountainous areas, meteorologist call them Katabatic or Anabatic Winds (more…)
Mature Thunderstorm Wind:
Thunderstorms are primarily local thermal weather phenomena (usually less than 5 miles to sometimes more than 30 miles in diameter), that are caused by either local surface heating , Air Mass Thunderstorms , or by weather systems such as fronts, converging winds, or troughs aloft that force upward motion of the surrounding air. From a surface wind perspective, thunderstorms, regardless of their cause can quickly and substantially modify wind direction and speed. (more…)
“Wind is the movement of air molecules in response to temperature and pressure differences in the atmosphere.” To properly select and site wind instruments the user must first understand the nature of the wind and its component parts that are the objective of the measurement. (more…)
