Objectives of research: 1) To explore mechanism of the seasonal moisture transport in Vietnam. 2) To determine the relationship between the moisture transport and the ENSO event, especially in ENSO years which heavy rainfall or severe drought occurred in Vietnam. 3) To propose the application of the moisture transport information for monitoring droughts (during El Niño) and heavy rainfall (during La Niña) over Vietnam. | MINISTRY OF NATURAL RESOURCES AND ENVIRONMENT VIETNAM INSTITUTE OF METEOROLOGY HYDROLOGY AND CLIMATE CHANGE VU VAN THANG CHARACTERISTICS OF MOISTURE TRANSPORT IN ENSO EVENTS IN VIETNAM Major Meteorology and Climatology Code 62 44 02 22 ABSTRACT OF EARTH SCIENCES DISSERTATION HA NOI-2016 The research is completed at VIETNAM INSTITUTE OF METEOROLOGY HYDROLOGY AND CLIMATE CHANGE Supervisors 1.

Rationale Located in the Asian monsoon region the climate of Vietnam is strongly influenced by the monsoon circulation and the ENSO events. Below-average annual rainfall was observed over Vietnam in El Nino years due to the strengthen convection in the Eastern Pacific. Whereas the westward-moving of this convection in La Nina years caused much more rainfall over Vietnam than average. It is indicated that the moisture transport plays an important role in tropical monsoon circulation mechanism as well as affects the weather and climate in Vietnam especially extreme event such as drought and heavy rain. Therefore this research titled Characteristics of moisture transport in the ENSO events in Vietnam is essential. 2. Objectives of research 1 To explore mechanism of the seasonal moisture transport in Vietnam. 2 To determine the relationship between the moisture transport and the ENSO event especially in ENSO years which heavy rainfall or severe drought occurred in Vietnam. 3 To propose the application of the moisture transport information for monitoring droughts during El Nino and heavy rainfall during La Nina over Vietnam. 3. Objects and research area - Objects of research Moisture transport Total moisture transport zonal and meridional moisture transport. Circulation component Zonal and meridional .
