Mosquitoes bothering you lately? Or have they been fewer in number than normal? Depending on your location in the Northeast you likely have differing answers. This map shows the precipitation minus the precipitation evapotranspiration, the total of evaporation and plant transpiration of water from the Earth’s surface. Preliminary research by the Northeast Regional Climate Center and Cornell Entomology “indicates that adult mosquitos (Culex) populations are typically high during periods of time when precipitation exceeds evaporation”, which are the positive values shown. The negative values represent evapotranspiration exceeding precipitation. One thing is certain – Chautauqua County’s positive value has skyrocketed in the past week! Science is so cool.
