European Centre for Medium-Range Weather Forecasts (ECMWF). A hindcast run was forced with the ECMWF wind stress and heat flux between 1990 and 2001. More detailed description of model configuration can be found in Wang and Yuan (2015) . We extracted equatorial waves by decomposing the results of the hindcast experiment. The wave decomposition method has been explained in Yuan et al. (2004) . The three-dimensional pressure and zonal velocity of the OGCM were projected onto the baroclinic vertical

1. Introduction East Asia is subject to frequent cold events during boreal winter. The long-lasting cold event in January and early February 2008 caused large economic and life losses in eastern China ( Zhou et al. 2009 ; Wen et al. 2009 ). In December 2009, several cold events occurred in the United States, Europe, and East Asia, bringing grave damage to these regions ( Wang and Chen 2010 ). A strong cold event struck East Asia in January 2016, causing snowfall and frigid weather in many

of 10%–30% over continental Europe relative to TRMM, and in particular less precipitation over the European Alps than TRMM. Vincent and Lane (2016a) compared TRMM and CMORPH estimates to rain gauges in New Guinea during a 1-month period and found a systematic overprediction in most locations for CMORPH, with many sites exceeding 10 mm day −1 and smaller positive and negative biases of less than about 5 mm day −1 for TRMM. That these results are inconsistent with those of Skok et al. (2016

the 40-yr European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40; Uppala et al. 2005 ) for the period 1982 to August 2002, and to the global analyses from BoM’s numerical weather prediction system thereafter (e.g., Hudson et al. 2011 ). Initial conditions for the ocean are obtained from the POAMA Ensemble Ocean Data Assimilation System (PEODAS), which assimilates available ocean observations using an ensemble Kalman filter (e.g., Yin et al. 2011 ). 2) The SINTEX-F model

Earth’s Radiant Energy System (CERES) Energy Balanced and Filled (EBAF) Edition 4.0 radiation on 1° × 1° grids, from Langley Atmospheric Science Data Center ( http://ceres.larc.nasa.gov/order_data.php ) ( Loeb et al. 2009 ). Observations from CERES begin in March 2000 and have been extended back in time ( Allan et al. 2014 ) using model results and other constraints, so that we use results from January 2000 on. The atmospheric computations here all utilize only the European Centre for Medium

Convection over the SCS–MC region exhibits significant multiscale variability, which remains a great challenge to the global atmospheric models, owing to the difficulties in representing convective processes in the tropical environment with contrasting land–ocean difference

The initial and lateral boundary conditions are obtained from the European Centre for Medium-Range Weather Forecasts (ECMWF) interim reanalysis (ERA-Interim) with a resolution of 1.5° × 1.5° at 6-h intervals. The sea surface temperatures (SSTs) are prescribed by ERA-Interim with a resolution of 1.5° × 1.5° at 6-h intervals. Both simulations (deforestation and control experiments) span 23 years from January 1979 to December 2001. The first 3 years were used as the spinup period and

All data above are daily data with horizontal resolution of 2.5° latitude × 2.5° longitude for 1984–2005. In this study, we focus on the boreal winter season (November–April). b. Methodology For the data analysis, we first removed the climatological annual cycle. Then a Lanczos bandpass filter ( Duchon 1979 ) was used to derive the HFW component ( A ′; <20 days), MJO

region running regional models for weather prediction using input conditions from the big centers like the European Centre for Medium-Range Weather Forecasts (ECMWF,) the Met Office (United Kingdom), and the National Oceanic and Atmospheric Administration (United States). A novelty of the current study is that it utilizes results from a convection-permitting state-of-the-art NWP model to highlight the biases in the input conditions from the high-resolution (9 km) deterministic forecast from ECMWF
