Atmospheric & Environmental Sciences

Southerly Mohawk-Hudson Convergence (SMHC) is a mesoscale phenomenon over New York’s Capital Region whereby a southwesterly wind flow over Eastern New York is channeled by the mountainous terrain westerly through the Mohawk River Valley and southerly through the Hudson River Valley. When these winds converge over the Capital Region, thunderstorms may suddenly erupt, disrupting air and ground traffic in the area. On rare occasions, these storms may be severe. This is the first comprehensive study to be conducted on this phenomenon. Climatology was compiled and showed that SMHC occurs on average at least twice a year. A case study was …
