Abstract

Abstract: In order to investigate the characteristic of Summer Monsoon in the Southern of Vietnam (SM) during Tropical Cyclone (TC) activity in the Vietnam’s East Sea (VES), we use the ERA Interim reanalysis data to determine the characteristic of SM intensity in two areas at three levels (1000mb, 850mb and 700mb). The first area (0 - 100N; 105 - 1100E) is used to examine the change of wind from Australian High and the second area (5 - 150N; 90 - 1050E)isused to analyze the change of wind from Mascarene High. These variations are investigated towards two characteristics: (1) Anomaly of wind compared with mean value and (2) Appearance frequency of wind in each value range. The results show that SM intensity during TC activity in the VES is less dependent on the time of year. SMI is stronger from 30% up to 85% of the mean values. In addition, during TC activity in the VES, frequency of SMI gets the maximum value in the range of VTB - 1,5VTB or 1,5VTB - 2VTB with the total of frequency from 55% to 75%.


Keywords: Characteristic of Summer Monsoon; Tropical Cyclone activity in the Vietnam’s East Sea.
