The predictability of two stratospheric sudden warming (SSW) events occurring in 2009 and 2010 is examined by conducting ensemble forecast using an AGCM. It is found that the predictable period of the vortex splitting SSW in 2009 is about 7 days, muc

Autor: MUKOUGAWA, Hitoshi, NOGUCHI, Shunsuke, KURODA, Yuhji, MIZUTA, Ryo, KODERA, Kunihiko

Publikováno v: 京都大学防災研究所年報. B. 59:145-152

In order to reveal the prediction skill as well as the key condition of the downward propagation of stratospheric planetary wave packets observed in early March of 2007, we conduct a series of ensemble reforecast experiments using the Ensemble Predic

Analysis on the Forcing Region of Sudden Stratospheric Warmings by Using Group Velocity of Planetary Wave Packets

Autor: UEDA, Manabu, MUKOUGAWA, Hitoshi, KODERA, Kunihiko, NOGUCHI, Shunsuke

Publikováno v: 京都大学防災研究所年報. B. 59:168-179

An analysis method to detect emanation regions and the associated emanation period of planetary wave (PW) packets inducing the sudden stratospheric warming (SSW) is developed. The method traces a 3D wave ray of a PW packet based on its group velocity
