Modification of a Successive Corrections Objective Analysis for Improved Derivative Calculations

摘要: Abstract The use of objectively analysed fields meteorological data for complex diagnostic studies and the initialization numerical prediction models places requirements upon objective method that derivatives grided be accurate free from interpolation error. A modification an analysis developed by Barnes provides improvements in analyses both field its derivatives. Theoretical comparisons, between analytical monochromatic warm comparisons actual weather are used to show potential new method. restores more amplitudes desired wavelengths while simultaneously filtering undesired wavelengths. These results also hold fire mend calculated gridded fields. Greatest were Laplacians height field; reduced variance undesirable very short 72 percent. Other ...
