The number of tropical cyclones (TCs) landed in Guangdong in 2004 is less than those of normal years, and there were no tropical cyclone landed in the western Guangdong. The first landing day is later, and the last landing day is earlier than normal. The intensities of these tropical cyclones are weaker on the whole, so that their benefits is greater than damage for Guangdong Province. The characteristics of the tropical cyclones landed in Guangdong in July, August and September during 1951-2004 are analyzed, and the result shows that the number of landing TCs is related to the position and intensity of the Northwest Pacific subtropical high. Three favorable and three unfavorable circulation patterns of the subtropical high for TC landing are identified.
