Keywords:Pseudo Global Warming Method, Dynamical Downscaling

We have estimated the global warming effects between current and future climate on the summer in the past 10 years of 2010 to 2019. The main area is Yokohama-City in Japan. Here we have performed regional climate simulations using the Multi-Scale Simulator for the Geoenvironment (MSSG) [1] on Earth Simulator 4. Dynamical downscaling from GPV data of Japan Meteorological Agency has been conducted with the horizontal spatial resolution of 320 meters. We have also considered the future climates both 2 K and 4 K warmer than the preindustrial climate using the pseudo-global warming method. The used data base for future climate is DDS5TK (5km-grid Dynamical Downscaling Dataset, SI-CAT DDS5TK [2]).
The obtained main feature is that the increases of the one-month averaged temperature is larger in the coastal area within about 1-km than those in the inland area. This is because the temperature of sea-breeze becomes higher in the future climate. These results have potential to contribute to the planning for sustainable future cities by area managers and others.
