on june 2, 2021, luo yali, a research fellow from the chinese academy of meteorological sciences, delivered the course "introduction to climate change science" to our postgraduate students.
with the theme of "extreme events and disaster risk management", this course is divided into eight parts: 1.definition and classification of extreme events; 2.basic characteristics of extreme events in china; 3.observed changes in extreme events and their causes; 4. changes in extreme events; 5. the ipcc assesses the progress of extreme event changes; 6. the basic definition of disaster risk management; 7. china’s future climate change risk forecast; 8.china’s comprehensive climate change risk management.
luo said that an "extreme event" or extreme weather event is a rare event in a specific area and time (within a year). there are many definitions of "rare", but the rarity of extreme weather events is generally equivalent to that the observed probability density function is less than the 10th or 90th percentile. in an absolute sense, extreme weather characteristics vary from region to region. a single extreme event cannot simply be directly attributed to man-made climate change because extreme events may occur naturally. luo introduced some familiar examples to illustrate that meteorological disasters may occur around us. therefore, we urgently need to evaluate the changes in extreme events to reduce the risk of people’s lives and property losses.
at the end of the course, luo arranged several thinking questions for everyone and encouraged students to actively ask questions, think and question diligently, and work hard to explore the vast scientific world. after class, the students asked questions around the teacher. the atmosphere of the whole teaching process was active and there was frequent interaction between teachers and students. the students said that the content of this course is rich and clear, and the teacher's introduction from the simple to the deep is very conducive to the students' understanding of knowledge, and everyone has benefited a lot.
luo is the second level research fellow of the chinese academy of meteorological sciences, the chief researcher of the state key laboratory of severe weather, doctoral supervisor, and the master supervisor of atmospheric science at the chengdu university of information technology. she mainly engaged in research on the mechanism and numerical simulation of heavy rain, strong convection, and cloud precipitation process, as well as the changes of extreme weather and climate. she has published more than 50 papers in domestic and foreign academic journals, international monographs, and national reports, including more than 40 journal papers included in sci.
