Further Discussion on Temperature Field During Storms and Thermal Score in Typhoon Actives and Damages of Typhoons

Abstract

Background: As we know, tropical cyclones or hurricanes (TCs) and typhoons are one of the natural disasters causing considerable damage to our life, economy and society. Objective: This study goal is to explore damages of typhoons and the temperature field during storms operating in the East Sea under the influence of cold air over time. Methodology: To determine the activities of the cold surge, the study analyzes the evolution of the 24-hour sea level barometric value in the region of 20-250N; 105-1150E. This is the area that is often affected first when KKL operates in East Asia in general and Vietnam in particular. Then, cold surge is considered to affect the area when the 24-hour transformer has a value greater than 1hPa. Results: Studies showed that the effects were investigated from 1991 to 2011 based on archived data from the National Centers for Environmental Prediction and the National Center for Atmospheric Research (NCEP-NCAR) and the number of typhoons were sourced from the International Best Track Archive for Climate Stewardship (IBTrACS). Conclusion: research showed that most typhoons occurred in August and September, which was related to high temperature in the summer season and the southwest monsoon in the area. In Vietnam, Although Typhoons has dissipated, the rain after typhoon No. 4 has left 3 people dead and missing, more than 7,000 houses were flooded, tens of thousands of hectares of agriculture and fisheries were damaged.
