Abstract: A statistical scheme for simultaneous analysis of the wind and geopotential height fields has been developed based upon optimum interpolation. The matrix weights applied to the observation vectors depend upon covariances ...

Abstract: The physical processes occurring within a perennial snow cover and at its surface are discussed with particular emphasis on monthly variations in Antarctic snow. Results of a one-year simulation of physical processes In ...

Abstract: For a 14-day period in late March and early April 1979, TIROS-N operational soundings have been compared with independent temperature analyses produced by the National Meteorological Center. Over the United States and ...

Abstract: Statistical properties of observed residuals from the Mesoscale Analysis and Prediction System (MAPS), a real-time data assimilation system, were investigated. Observed residuals are defined as differences between rawinsonde ...

Abstract: The Second Prospectus Development Team (PDT-2) of the U.S. Weather Research Program was charged with identifying research opportunities that are best matched to emerging operational and experimental measurement and modeling ...

Abstract: Using an 8-day series (18?26 August 1975) of multivariate statistical analyses of European radiosonde data together with a measure of analysis error, we have estimated error statistics from 959 Nimbus 6 temperature profiles ...

Abstract: c investigation is supposed to be objective and strictly logical, but this is not always the case: the process that leads to a good conclusion can be messy. This narrative describes interactions among a group of scientists ...

Abstract: A multivariate statistical analysis procedure has been developed for estimating geopotential height h and wind (u, v) on a global latitude-longitude grid. Estimates are obtained by modifying the ?first guess? from a ...

Abstract: An unusual, isolated hailstorm descended on Boulder, Colorado, on the evening of 24 June 2006. Starting with scattered large, flattened, disk-shaped hailstones and ending with a deluge of slushy hail that was over 4 cm ...

Abstract: The 24 June 2006 Boulder hailstorm produced very heavy precipitation including disklike hailstones that grew with low density. These disklike hailstones, 4?5 cm in diameter, are unusual, and some of them appear to have ...
