Examining the land-lake-atmosphere interactions of the May 5, 2003 severe weather event over southwest Michigan
The thermodynamic and dynamic structure leading to the convective initiation of this system is explored through a series of 400m horizontal resolution Weather Research and Forecasting Model (WRF) simulations with 101 vertical levels. Lake surface temperatures are altered in subsequent simulations to test the sensitivity of this type of storm initiation to lake surface properties and the depth of the stable boundary layer over the water, as well as to simulate future climate scenarios. Understanding this fine-scale feature is important for evaluating future climate simulations over the Great Lakes region. Existing climate models may not accurately represent this land-lake-atmosphere interaction over the region due to lower horizontal resolution, which could lead to discrepancies in distribution and intensity of rainfall.
