![]() 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. KCMH, 35% 7 mi, 46 ft KTZR, 25% 8 mi, 135 ft KOSU, 22% 9 mi, 135 ft KLCK, 18% 11 mi, -26 ft © OpenStreetMap contributors Rickenbacker International Airport (KLCK, 18%, 11 mi, south, -26 ft elevation change).Ohio State University Airport (KOSU, 22%, 9 mi, northwest, 135 ft elevation change).Bolton Field (KTZR, 25%, 8 mi, southwest, 135 ft elevation change).Port Columbus International Airport (KCMH, 35%, 7 mi, east, 46 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 4 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. It was heavy, wet snow that caused widespread tree and power line damage. At one point, 90,000 people were without power.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 type of snowfall in this storm was significant. ![]() The highest snow report was in Geauga County, with 26.3 inches of snow from Nov. Places like Toledo, Columbus and Cincinnati picked up 2-4 inches of snow, which is a lot for the end of November.īut the snow really piled up in northeast Ohio. It started as rain in western Ohio, then turned to accumulating snow in northeast Ohio. The first big snowstorm of last winter began on Nov. This weekend's snowfall should just make the pavement wet, but last fall, we saw a major snowstorm that brought two feet of snow to some spots in northeast Ohio. ![]() We record our first snowfall when we see at least 0.10 inches of snow. Seeing snow this weekend, especially in northern Ohio, isn't unusual.
