With this model, numerical experiments of a coastal front over Kanto Plane occurred on 5 December 2004 associated with a highly developed low were carried out on the supercomputer of CeNSS because the high-resolution experiments in a large domain requires powerful computer resources. The model results showed that the three-dimensional structure of the coastal front was well reproduced as the model grid resolution becomes finer, from 2 km to 0.5 km. This result suggests the turbulent kinetic energy is estimated more appropriately at finer resolution. The performance of the high-resolution model was examined further by energy spectra of horizontal winds as a function of wave number (k). It was found that the energy spectra obeys approximately the k(exp -5/3) spectral character of the observational spectra; this suggests that the high-resolution model simulates well the atmospheric condition., 資料番号: AA0049212017, レポート番号: JAXA-SP-05-017}, pages = {106--111}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {気象の高解像度数値予報}, volume = {JAXA-SP-05-017}, year = {2006} }
