Front, in meteorology, interface or transition zone between two air masses of different density and temperature; the sporadic flareups of weather along this zone, with occasional thunderstorms and electrical activity, was, to the Norwegian meteorologists
winter low-pressure systems have large horizontal pressure differences and are always accompanied by strong jet-stream winds aloft. In the northeasternUnited States, windstorms that occur as particularly strong low-pressure systems and move northward along the Atlantic Coast are called “nor’easters....
Capacity factor-temperature correlations. Correlations between CF and surface temperature over the selected region as a function of the choice of filtered locations for the 37-year interval covered in the study: (a) correlation with the SH annual average surface temperature; (c) correlation with ...
It is defined as the difference between temperature at 850 hPa and temperature at 500 hPa, plus the dew point temperature at 850 hPa, and then minus the difference between the temperature at 700 hPa and the dew point temperature at 700 hPa. The TT index is defined as the sum of two ...
The direct effect of sea surface temperature (SST) structures on the extratropical atmosphere at the daily time‐scale is generally masked by the large variability associated with atmospheric dynamics. With 25 years of daily SST and surface wind observational products, obtained with data from buoys,...
First, we consider measurements aloft using the lidar measurements at C1 to quantify the impact that the southern portion of the Thunder Ranch wind plant has on the long-term lidar data. Although the use of numerical simulations allows for the concurrent availability of data with and without ...
Figure 1 additionally compares monthly vertical ozone, temperature, and dew point profiles with model values in the same locations as the measurements. The comparisons indicate extremely good agreement considering the coarseness of the model resolution. Figure 1. Comparison of monthly-averaged vertical ...
precipitation forms and falls out as rain. This is when the downdraft portion of the thunderstorm occurs. Rain-cooled air sinks along with the downward drag from falling precipitation. The harder the rain falls, the stronger the downdraft can become. Also, stronger atmospheric winds aloft are som...
This slackening is related to the temperature structure of the storm. Air is warmer in the core of a tropical cyclone, and this higher temperature causes atmospheric pressure in the centre to decrease at a slower rate with height than occurs in the surrounding atmosphere. The lessened contrast ...
摘要:A wind tunnel test of the wind turbine airfoil Riso-B1-18 equipped with an Active Trailing Edge Flap (ATEF) was carried out. The ATEF was 9% of the total chord, made of piezo electric actuators attached to the trailing edge of a non-deformable airfoil and actuated using an (electri...
