Observations of misovortices within the 7 January 2014 Long Lake-Axis-Parallel lake-effect snow band during the Ontario Winter Lake-effect Systems Project
Recent lake-effect snow field projects in the Eastern Great Lakes region [e.g., the Long Lake-Axis-Parallel (LLAP; 2010-2011) Project and the Ontario Winter Lake-effect Systems (OWLeS; 2013-2014) Project] have revealed the presence of misovortices with diameters between 40 and 4000 m within LLAP …

The Role of Upstream Lakes in Determining Downstream Severe Lake -Effect Snowstorms
A severe lake-effect snowstorm on 25--26 December 1993 was successfully modeled using the Penn State/NCAR MM5 model at 7 km grid resolution. Another simulation performed with Lake Michigan removed from the domain resulted in a two-thirds reduction in snowfall maxima, reduced vertical ascent (50% …

The Structure and Intensity of Winter Mesoscale Lake -Effect Circulations Associated With an Isolated Lake
… understand and predict the strength of mesoscale lake-effect circulations a simple function, called the lake-effect intensity index, was developed using the dimensional analysis technique. The intensity index was found to be equivalent to scaling the Froude number by a dimensionless quantity …

Boundary layer temporal evolution observed by doppler lidar upwind of a lake-effect snow event
… Doppler Wind LiDAR (LiDAR) was deployed during a lake-effect snow event over Lake Michigan to develop a method of processing and reviewing the data collected by the LiDAR, create a conceptual model of the temporal evolution of the atmospheric boundary layer on the lake’s upwind shore, and …

Radar observations of misovortices within multiple long-lake-axis-parallel lake-effect bands during the OWLeS project
The Ontario Winter Lake-effect Systems (OWLeS) Project collected a wealth of data on several lake-effect storms in the vicinity of Lake Ontario during the winter of 2013-14. Of all lake-effect band archetypes, long- lake-axis-parallel (LLAP) bands are the most intense, bringing the highest snowfall …

A recent spatial, temporal, and meteorological climatology of thundersnow across the contiguous United States
… that were used were cyclone, orographic, lake effect, and coastal cyclone. These categories were then analyzed and compared to identify spatial and temporal patterns. Regionally, hotspots were found in the Great Plains to the Upper Midwest, Colorado, the East Coast, and areas adjacent to …

Snowstorms in Upstate New York: synoptics, spatial modeling and temporal variability
… New York, a subsection of the eastern Great Lakes region, in a series of chapters organized as journal articles. The first article develops a classification scheme to categorize snowstorms in Central New York from the 1985/86 season to the 2014/15 season. Twelve different snowstorm types were …

Trend Reversal in Lake Michigan Contribution to Snowfall
One of the most notable ways the Laurentian Great Lakes impact the region’s climate is by augmenting snowfall in downwind locations during autumn and winter months. Among many negative consequences, this surplus of snow can cause substantial property damage to homes and can escalate the number of …

Effects of Air Temperature and Lake Ice on Snowfall on the South Shore of Lake Superior
Lake Superior is a forcing factor for local weather systems, causing substantial amounts of lake effect snow in the winter (particularly on the south shore). This study assesses decreasing ice cover of Lake Superior and its effects upon synoptic weather factors. Data were collected from eleven …

Climate Change in Buffalo, NY
… New York, located along the eastern shore of Lake Erie. My hypotheses are that average winter temperatures and snowfall should be increasing, Lake Erie should be freezing at a later date, and Lake Erie’s ice cover should affect snowfall amounts. The warmer temperatures would lead to Lake …

The role of lake enhancement in the evolution of the 2011 Chicago-area Groundhog's Day blizzard
… This study analyzes the role that the Great Lakes played in modifying this cyclone. Two different Weather Research and Forecasting (WRF) simulations were conducted, one featuring the lakes and the other with the lakes removed. Prior to the arrival of the comma head, reverse lake effect …

An East Coast Winter Storm Precipitation Climatology
… non-ECWS, if applicable. The issue of excluding lake effect snow (LES) is also addressed. This same climatology is developed for rapidly deepening ECWS, termed ?bombs? by previous studies. A sensitivity analysis of the ECWS precipitation climatology is investigated considering the following …
