Summary Account

The atmospheric boundary layer spans from the earth's surface to the height of about 1km. Since this layer is turbulent, it undergoes efficient exchanges of the momentum, heat, mass, and so on. They eventually affect the atmospheric phenomena as a whole. However, such processes of turbulence are still 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.

Numerical Simulation
Large Wind Tunnel

Numerical Simulation
Horizontal sectional view of the vertical velocity in the atmospheric boundary layer, obtained from a high-resolution numerical simulation. The upward flow (red) and the downward flow (blue) make up a cellular pattern of the convection.

Large Wind Tunnel
This tunnel is one of the largest wind tunnels for the meteorological research in Japan. By controlling the wind speed as well as the air temperature, it is used to conduct a variety of experiments for the atmospheric boundary layer.

Surface Layer Meteorological Observation System

Surface Layer Meteorological Observation System
This system consists of various sensors on and around the 6m-height tower. In addition to soil moisture and soil temperature, it measures wind speed, wind direction, temperature, humidity, and solar radiation in the surface boundary layer.
