Abstract：The precipitation, high winds (with wind speed at least 10.8m/s) and direct economic losses caused by tropical cyclones (TCs) in Guangdong during 2004-2014are studied to disclose the relationships between the influence of TCs and meteorological factors, and build an assessment model for the influence of TCs. The seashore areas of Guangdong are affected frequently by the TCs precipitation and high winds and the economic loss rates and the disaster frequencies are much bigger in the southwestern and eastern seashore areas of Guangdong. There are good power law relations between the economic loss rates and the TCs precipitation and high winds. According to the power law relations, the meteorological condition threshold can be calculated for the different level of economic loss rates. Then the meteorological condition threshold can be used to assess the influence of TCs. The evaluations of economic loss rates by TCs influencing Guangdong using the meteorological condition threshold during 2004-2014 are compared with the actual economic loss rates. The results show that the assessments are reasonable, which means this method can be used to assess the influence of TCs in Guangdong.
