RISAdjustments for Wind Sampling Errors in an Estimate of the Atmospheric Water Budget of the Mississippi River Basin
Publisher: American Meteorological Society
Abstract: The spurious mass divergence found in observed and analyzed atmospheric wind fields causes errors in estimated energy flux divergence. An objective method for correcting these errors in radiosonde-based atmospheric water ...
Derived Distributions of Storm Depth and Frequency Conditioned on Monthly Total Precipitation: Adding Value to Historical and Satellite-Derived Estimates of Monthly Precipitation
Publisher: American Meteorological Society
Abstract: The stochastic precipitation model in which storms arrive as a Poisson process and have gamma-distributed depths previously has been shown to display useful aggregation properties. Here the disaggregation properties of ...
Performance Assessment of a New Stationarity-Based Parameter Estimation Method with a Simplified Land Surface Model Using In Situ and Remotely Sensed Surface States
Publisher: American Meteorological Society
Abstract: his study evaluates the performance of a new stationarity-based method for parameter estimation of a simple coupled water and energy balance model using in situ and remotely sensed surface soil moisture [from Advanced ...
Comparison of Soil Wetness Indices for Inducing Functional Similarity of Hydrologic Response across Sites in Illinois
Publisher: American Meteorological Society
Abstract: The comparative ability of four soil wetness indices to normalize soil moisture dependence of rootzone fluxes across a range of sites in Illinois is investigated. The soil wetness indices examined are various transformations ...
A New Two-Dimensional Physical Basis for the Complementary Relation between Terrestrial and Pan Evaporation
Publisher: American Meteorological Society
Abstract: Archived global measurements of water loss from evaporation pans constitute an important indirect measure of evaporative flux. Historical data from evaporation pans shows a decreasing trend over the last half century, but ...
Central U.S. Atmospheric Water and Energy Budgets Adjusted for Diurnal Sampling Biases Using Top-of-Atmosphere Radiation
Publisher: American Meteorological Society
Abstract: The water and energy budgets of the atmospheric column over the Mississippi River basin are estimated using 18 yr (1976?93) of twice-daily radiosonde observations, top-of-atmosphere net radiation estimates from the Earth ...
Regional and Seasonal Estimates of Fractional Storm Coverage Based on Station Precipitation Observations
Publisher: American Meteorological Society
Abstract: Simulated climates using numerical atmospheric general circulation models (GCMS) have been shown to he highly sensitive to the fraction of GCM grid area assumed to be wetted during rain events. The model hydrologic cycle ...
What Do Rain Gauges Tell Us about the Limits of Precipitation Predictability?
Publisher: American Meteorological Society
Abstract: generalizable method is presented for establishing the potential predictability for seasonal precipitation occurrence using rain gauge data. This method provides an observationally based upper limit for potential predictability ...
Stochastic Modeling of Daily Summertime Rainfall over the Southwestern United States. Part II: Intraseasonal Variability
Publisher: American Meteorological Society
Abstract: The intraseasonal variability of summertime precipitation over the southwestern United States is examined using stochastic daily occurrence models combined with empirical daily rainfall distributions to document 1) the ...
The Potential Predictability of Precipitation Occurrence, Intensity, and Seasonal Totals over the Continental United States
Publisher: American Meteorological Society
Abstract: sing weather station data, the parameters of a stationary stochastic weather model (SSWM) for daily precipitation over the contiguous United States are estimated. By construct, the model exactly captures the variance ...
