COMET_CASE_034: COMET Case Study 034:New Jersey Flood:Terrain Locked Convect


On 12 August 2000, flooding rains hit the state of New Jersey. The rains were associated with regenerative warm-topped convection, and in many areas, including the hardest hit Sparta, roads were closed, bridges washed out, mudslides occurred and motorists were stranded. Terrain-locked convection over Sparta resulted in over 9 inches of rain in 8 hours, with media reports of as much as 14 inches. Rainfall rates were as high as 4 inches per hour.


This case provides an example of terrain-locked convection.
