Winter storms can have a significant impact on society, yet remain a challenge to accurately forecast.
The emergence of polarimetric radars has allowed for better detection of precipitation type, including transitions from rain to snow and from freezing rain to ice pellets.
In addition, the information we get about particle shape can be used to determine ice crystal habits, which tells us about the internal microphysics of the storms.
A list of my publications about winter storms can be found below.
