The ensemble mean fields available from this page are simple numerical averages of the four concurrent members. Due to the high resolution of the solutions, means calculated in this manner are not appropriate for storm scale fields such as updraft helicity, updraft velocity, etc. This method can also give misleading information for simulated reflectivity fields when precipitation is convective in nature. Neighborhood probabilities, which are appropriate for storm scale fields (as well as reflectivity output), are also available from the HopWRF home page.
