While lakes make up less than 2% of Earth’s surface area, they bury over three times more carbon in their sediments than all of the world’s oceans combined 2.This means on a per area basis lakes bury over 100 times more carbon than the oceans. Relevance. Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. Author: Heather Waldman The lower layer of air, heated up by the lake water, picks up water vapor from the lake and rises up through the colder air above; the vapor then freezes and is deposited on the leeward (downwind) shores.. Estimates of lake-induced spatial changes of six climate variables (precipitation, mean minimum and mean maximum temperatures, cloud cover, vapor pressure, and wind speed) were derived for the entire Great Lakes basin. By mid-century (2050), average air temperatures are projected to increase by 3°F to 6°F (1.7°C to 3.3°C). 22 (1996): 845-863.

These modifications are known collectively as lake effects and extend from the microscale to the synoptic scale. 22(4):845-863 Internat. Great Lakes Res., 1996 Impacts ofthe Great Lakes on Regional Climate Conditions Robert W. Scott andFloyd A. Huff Illinois State Water Survey 2204 Griffith Drive Champaign, Illinois 61820 ABSTRACT. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. Favorite Answer. Lake-effect snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water. Liz Kirkwood, environmental attorney and executive director of FLOW (For Love of Water) based in Traverse City. - Articles from The Weather Channel | weather.com Climate change is already beginning to affect plants and animals that live in freshwater lakes and rivers, altering their habitat and bringing life-threatening stress and disease. because of size and location lake michigan plays the biggest part in creating the 'lake affect' While progress to restore and protect the Great Lakes has been made, including the reduction of toxic chemicals, challenges remain with issues such as invasive species and nutrients. Lakes play a much greater role in global carbon cycling than their area would otherwise predict. The Western region of the Lakes tends to be drier, while the Southeast area tends to have far more precipitation (“lake-effect” snow and rain). How Do the Great Lakes Affect Temperature?

They primarily affect the climate in three ways: by reducing temperature, decreasing energy usage and cleansing the air by removing a host of air pollutants. The cooling effect on the climate is facilitated by the leaves of trees, which is a process called evapotranspiration. Lake effect precipitation can occur downwind when major weather systems move over the lakes.

Heavier rainfall is increasing runoff from farms and cities, which leads to more nitrates, phosphates, E Coli, and other pollutants entering waterways. Changnon, Stanley Jr A., and Douglas M. A. Jones. Lake effect snow buries parts of the Great Lakes in December 2016. Our warming climate is already causing negative effects like declining ice cover and increasing surface temperatures, changes that can be majorly disruptive to a lake's normal processes.
