Data Assimilation by Morphing Fast Fourier Transform Ensemble Kalman Filter for Precipitation Forecasts using Radar Images
The FFT EnKF takes advantage of the theory of random fields and the FFT to provide a good and cheap approximation of the state covariance with a very small ensemble. The method and predecessor components are explained and the method is extended to the case of observations given on a rectangular subdomain, suitable for assimilation of regional radar images into a weather model.
متن کاملSpectral characteristics of background error covariance and multiscale data assimilation
The spatial resolutions of numerical atmospheric and oceanic circulation models have steadily increased over the past decades. Horizontal grid spacing down to the order of 1 km is now often used to resolve cloud systems in the atmosphere and sub-mesoscale circulation systems in the ocean. These fine resolution models encompass a wide range of temporal and spatial scales, across which dynamical ...
متن کاملBackground error covariance estimation for atmospheric CO2 data assimilation
[1] In any data assimilation framework, the background error covariance statistics play the critical role of filtering the observed information and determining the quality of the analysis. For atmospheric CO2 data assimilation, however, the background errors cannot be prescribed via traditional forecast or ensemble-based techniques as these fail to account for the uncertainties in the carbon em...
متن کاملAssimilating Conventional and Doppler Radar Data with a Hybrid Approach to Improve Forecasting of a Convective System
A hybrid ensemble adjustment Kalman filter—three-dimensional ensemble—variational (EAKF-En3DVar) system is developed to assimilate conventional and radar data, and is applied to a convective case in Colorado and Kansas, USA. The system is based on the framework of the Weather Research and Forecasting model’s three-dimensional variational (3DVar) and Data Assimilation Research Testbed. A two-ste...
متن کاملSensitivity of Convective Initiation Prediction to Near-Surface Moisture When Assimilating Radar Refractivity: Impact Tests Using OSSEs
The Advanced Regional Prediction System (ARPS) three-dimensional variational (3DVAR) system is enhanced to include the analysis of radar-derived refractivity measurements. These refractivity data are most sensitive to atmospheric moisture content and provide high-resolution information on near-surface moisture that is important to convective initiation (CI) and precipitation forecasting. Observ...
