Manual synoptic climate classification for the east coast of New England (USA) with an application to PM2.5 concentration

摘要: This study presents a manual synoptic climate classification for the East Coast of New England with an application to regional pollution. weather was classified into 9 all-inclusive types: Canadian High, Modified Gulf Maine Return, Atlantic Frontal Overrunning-Continental, Overrun- ning-Marine, and Tropical Disturbance. High are domi- nant patterns at Boston, Massachusetts, while Disturbance, types least frequent. Properties were determined 07:00 h Local Standard Time (LST) each day in Boston. The coldest driest type is hottest, most humid generated by Return. system, applied airborne fine particle mass concentra- tions aerodynamic diameter ≤2.5 µm (PM2.5), showed significant differences between transport from north northwest had low PM2.5, south southwest high PM2.5 concentrations. system also has potential applications ranging studies insect migration analyses change.
