Coupled chemistry-climate models are being increasingly used to tackle the problem of understanding the mechanisms for driving changes in past, present and future atmospheric composition. Given the computational overheads of running these types of models the chemical mechanisms which are used are often chosen for their speed of simulation.
China's economic growth is expected to continue into the next decades, accompanied by a sustained urbanization and industrialization. The associated increase in demand for land, water resources, and rich foods will deepen the challenge to sustainably feed the population and to balance agricultural and environmental policies.
Seminar: Large Increasing Trend of Tropical Cyclone Rainfall in Taiwan and the Roles of Terrain and Southwest Monsoon
Taiwan, which is situated in one of the main paths of western North Pacific tropical cyclones (TCs), has experienced a dramatic increase in typhoon-related rainfall, with nine of the top 12 typhoons in total rainfall since hourly rainfall observations started in 1960 have occurred in the 21st century. This record breaking increase has led to suggestions that they are the manifestation of the effects of global climate change include global warming. Typhoon rainfall intensity is analyzed with respect to typhoon tracks that are in different regimes relative to the meso-α scale terrain.
Satellite observations offer a powerful source of data to support air quality management, by providing information about air pollutant concentrations, trends, and transport, particularly where no other monitors are available; identification of pollution sources to constrain emissions estimates; and regional characterization of air pollutant distributions to support air monitor siting decisions.
Seminar: Reducing uncertainty in regional climate projection: New challenge for coupled ocean-atmosphere dynamics
Global mean temperature has risen for the past century and is projected to rise even more in response to the increasing atmospheric CO2 concentrations. Precipitation change is of vital importance to societies but precipitation projections are intrinsically challenging as they change sign from one region to another. Recent studies show that in the tropics, radiatively forced changes in precipitation and atmospheric circulation are tightly coupled to spatial patterns of ocean surface warming.
