CSTAR research on precipitation and tropical cyclones in New England indicates precipitation is maximized when…

• Upper-level anticyclonic outflow results in an enhanced upper-level jet northwest-northeast of the surface cyclone.

• The right entrance region of the upper-level jet is located over the potential heavy rain area.

• Enhanced low-level jet develops along with enhanced θe advection.

• Precipitation is frequently enhanced by interactions between the low-level jet and coastal fronts / topography.
