Onn Tanpèt: Yon monte anòmal nivo lanmè a ki vini avèk yon ouragan oswa lòt gwo tanpèt, epi wotè li se diferans ant nivo sifas lanmè yo obsève ak nivo ki te ka genyen si pa t gen siklòn nan. Anjeneral, pou estime onn tanpèt la, ou fè soustraksyon lamare nòmal oswa lamare wo nan lamare tanpèt ki obsève a. Onn tanpèt la kapab rive nan wotè ki depase 20 pye, epi li kapab deplwaye sou yon distans anpil santèn mil nan litoral la.

Storm Surge: An abnormal rise in sea level accompanying a hurricane or other intense storm, and whose height is the difference between the observed level of the sea surface and the level that would have occurred in the absence of the cyclone. Storm surge is usually estimated by subtracting the normal or astronomic high tide from the observed storm tide. Storm surge can reach heights well over 20 feet and can span hundreds of miles of coastline.
