Large-scale Dynamics and Thermodynamics of Ice Storms
Ice storms (freezing rain) can have enormous impacts on life and property. The infamous 4 - 10 January 1998 Ice Storm resulted in > 100 mm (4 in.) of ice in New England, eastern Ontario, and southern Quebec, leaving millions without power for weeks!
A more recent severe ice storm in Slovenia in late January and early February 2014 produced > 125 mm of ice accumulation, and was likely the most expensive natural disaster in that country's history (see the ridiculous pictures below). This severe ice storm was associated with a "Rex Block", a stagnant upper-tropospheric pattern that features a strong ridge to the north and cut-off cyclone to the south (see image below)
my primary research objectives in this area are to:
- Improve understanding of the precursor planetary- and synoptic-scale dynamics that result in long-duration severe freezing rain events.
- Assess how freezing rain frequency, duration, intensity, and areal coverage have changed and are changing in a warming world.
