; Miyoshi and Kunii 2011 ). Another important parameter is the multiplicative inflation, whose role is to prevent underestimation of the forecast error covariance leading to filter divergence ( Anderson and Anderson 1999 ). In this work, the adaptive inflation technique developed by Miyoshi (2011) and implemented within WRF-LETKF by Miyoshi and Kunii (2012) is used. This method allows an online estimation of a location and time-dependent optimal inflation factor based on the innovation statistics
