A full barb = 10, and a short barb = 5.The units are MPH for the US cities, and m/s for Canada.The barbs indcate the direction and speed of the wind, rounded to the nearest 5.The model data we receive is interpolated down to 1000 millibars,īut over high terrain only data that is near or above ground level is displayed.ĭata below ground level has no physical meaning and is omitted. Tropospheric Time-Height Cross Section Conditions for the lower troposphere (up to 500 millibars)Īre shown in profile. With things like mountainous terrain, or sea breezes. Thus these models may notĭo a good job of forecasting very localized weather such as might be associated Represented indirectly by using parameterizations). Of the land surface, and the sub-grid scale distribution of thunderstorms are ![]() Than the grid resolution (although certain aspects such as the small-scale roughness The models cannot directly discern any features of the terrain or atmosphere smaller In fact, the the forecasts are based on the grid point nearest the city in question. Forecast meteograms are given for selected US cities. These are not the "official" forecasts, though in mostĬases they should resemble them rather closely since the official forecastsįor your region are based on these models to various extents. No interpretation, corrections, or other objective or subjectiveĬhanges have been made. Models at the National Centers for Environmental Research (NCEP) of the National Provided by COLA, these data are "as is." They are straight from the computer Keep in mind that like all the other model forecast information "big picture", but it can be difficult to tell what will transpire in your particular Maps, or satellite "movies" are good for giving an overall perspective of the Most people are rather stationary with respect to the atmosphere (unless youĭo a lot of traveling), so a person's natural perspective is Eulerian. Using a meteogram, one can get a feel of how conditions change and evolveĪt a stationary point (termed the "Eulerian" perspective). May be plotted, either as line graphs, bar graphs, symbols, numbers, shading,Įtc. Time progresses from left to right across the figure. #Aeroweather pro seriesOne very useful way to look at a time series of meteorologicalĭata at a particular point is by ploting the data in a "meteogram."
