![]() Potentially go to space and allow the planet to cool. Naturally occurring Greenhouse gases such as carbon dioxide (CO2) and water vapor absorb radiation coming from the earth that would Strikes the earth’s surface and warms it up. To understand how global warming and pollution affect the earth’s climate, one first has to understand how the planet’s temperature is regulated. This leads to an increase in rainfall and a reduction in snowfall in areas normally affected by lake effect snow, especially on the southern Great Lakes. In a climate change setting, the flowing air is not as cold, and the water contained in the forming clouds does not freeze into snow before it comes back down. This is especially common in cities like Buffalo, NY, or Cleveland, OH. Heavy evaporation from the lake surface forms clouds thatĬannot contain the evaporated water, and some of it comes back down as snow. Lake effect snow is caused when cold winter air flows over the warmer waters of a large lake. “According to numerical models of the atmosphere, this is what we expect with a planet that is undergoing greenhouse warming.” “We keep going back and forth like this a couple of days of heavy rain, then things dry out quite aīit,” Rogers says. Precipitation events,” as they’re known in meteorologist circles). Especially in the summer, the state goes without rainfall for long periods of time, followed by heavy rainstorms (or “extreme In a given time period − have become much larger. Increased humidity as part of a changing climate in Ohio also goes along with another weather phenomenon: precipitation extremes − very large or very small amounts of rain or snowfall Likely factor in explaining the changing cloud cover. “Increased cloud cover acts like a blanket and traps heat that would otherwise escape into the atmosphere,” Rogers suggests, adding that additional humidity in the air is a Highs and nighttime lows − for Columbus has steadily decreased over the past 60 years, a phenomenon which some climate scientists suggest could be one of the first indicators of a warming The diurnal temperature range − the difference between daytime The effect of humidity on Ohio’s climate is especially visible when looking at nighttime temperatures in the state. I think the temperature changes are here to stay,” he adds. “Humidity traps more heat, air then retains more humidity, and so on. ![]() “I see it continuing also because in Ohio, there’s a very strong link between humidity and moisture, which will ensure that temperatures will keep going up,” RogersĮxplains. Why summers are getting hotter across the Great Lakes region. But greenhouse gases in the atmosphere are not the only reason Those of the 1930s Dust Bowl, recent summers like 2002, 20 will be very high on that list, according to Rogers. While the warmest summers on record are still Rogers suggests that the climate in Ohio has been getting steadily warmer over the years, and will likely continue to do so in the future. Recently, his research has included analyses of how atmospheric circulationĬan create different types of regional weather − how changes in a circulation pattern called the Pacific North American Pattern can cause milder but wetter winters in the Ohio River Valley, North America, and often focuses his research on the weather patterns of Ohio and the Southeastern United States. Rogers studies climate variability in the United States and Jeffrey Rogers, Professor in the Department of Geography at Ohio State University. ![]() Scenarios in a world affected by climate change. Weather patterns makes them an invaluable resource not only for those concerned about the impacts of today’s weather, but also for those responsible for adapting to new weather The climatologists’ knowledge of their state’s climate and Weather observers across their state, compile and verify weather data, and make it available to interested parties. At the same time, water is added from precipitation (tan arrows) in the form of rainĪnd snow, as well as through inflow from basin streams (green arrows), upstream lakes (purple arrows) and ground water.ĭid you know that almost all US states have a state climatologist? These researchers, in addition to duties within universities or governmental agencies, manage networks of volunteer Flow out to other bodies of water and to the Atlantic (purple arrows) (red arrows) that removes water from the lakes’ surface. Air temperature and wind control evaporation ![]() The Great Lakes water cycle is driven by a number of climatological factors.
