Japan has experienced natural disaster conditions brought by torrential rain, typhoons, ans so on. The global warming is also an urgent issue. Thus, meteorology is an increasingly important branch of the planetary science. We are to study the following issues of the meteorology, by making use of various facilities of the Meteorological Research Institute of the Japan Meteorological Agency.
1. Atmospheric boundary layer - studies on the atmosphere close to the earth's surface -
The atmospheric boundary layer spans from the earth's surface to the height of about 1km. Since this layer is highly turbulent, it undergoes efficient exchanges of the momentum, heat, mass, and so on. They eventually affect the whole atmosphere. However, such processes of turbulence are yet uncertain. By means of numerical simulations, laboratory experiments, and field observations, we study the atmospheric boundary layer to improve the parameterization for those processes in the numerical weather prediction.
2. Data assimilation and predictions of local heavy rainfalls
Topics on data assimilation and weather prediction systems will be given in this lecture course. It is quite difficult to predict local heavy rainfall events, which have been called as 'Guerrilla heavy rainfalls" theses days, due to their small horizontal scale and large temporal variation. For the successful prediction, we need data assimilation techniques, which provides a bridge between "observations" and "simulations". This lecture coarse briefly presents 1) observations on meso-convective systems, 2) simualtion models, 3) data assimilation theory, and 4) mechanisms of local heavy rainfall events.
