![]() While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. We assume no responsibility for any decisions made on the basis of the content presented on this site. Weather data is prone to errors, outages, and other defects. The information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. Time zones for airports and weather stations are provided by. Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database. Land Use data comes from the Global Land Cover SHARE database, published by the Food and Agriculture Organization of the United Nations.Įlevation data comes from the Shuttle Radar Topography Mission (SRTM), published by NASA's Jet Propulsion Laboratory. This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.Īll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition, by Jean Meeus.Īll other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis. To get a sense of how much these sources agree with each other, you can view a comparison of Columbus and the stations that contribute to our estimates of its temperature history and climate. KCSG, 60% 5 mi, 151 ft KLSF, 36% 8 mi, -10 ft KAUO, 5% 28 mi, 535 ft © OpenStreetMap contributors Auburn-Opelika Robert G Pitts Airport (KAUO, 4.7%, 28 mi, northwest, 535 ft elevation change).Lawson Army Airfield (KLSF, 36%, 8 mi, south, -10 ft elevation change).Columbus Airport (KCSG, 60%, 5 mi, northeast, 151 ft elevation change).The stations contributing to this reconstruction are: The estimated value at Columbus is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Columbus and a given station. There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Columbus.įor each station, the records are corrected for the elevation difference between that station and Columbus according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. Rain totals do not look very impressive at this time, but a dry airmass with cooler temperatures will return by the weekend.This report illustrates the typical weather in Columbus, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016. The next best chance for rain is on Friday. As the high pressure starts moving toward the Atlantic, southerly winds will start driving moisture back into the area ahead of a frontal system. ![]() Lows will follow suit as they return to the 50s by Thursday morning. As the high-pressure slides eastward, temperatures will start to warm up into the 70s once again starting on Wednesday. Those winds will relax on Tuesday but cool highs and lows in the 40s and 60s will stick around. Breezy northwest winds as high as 20 mph will also remain in the forecast for Monday. The cool weather will not stop there as highs for Monday are likely to rise into the upper 60s under mostly sunny skies. This will bring in cool, breezy winds into the night allowing lows to fall into the upper 40s and low 50s. ![]() (WALB) - A few disturbances pushing southeast are helping to reinforce the northwest flow into our area.
