The Effects of Remotely Sensed Plant Functional Type and Leaf Area Index on Simulations of Boreal Forest Surface Fluxes by the NCAR Land Surface Model
(American Meteorological Society, 2000)The land surface models used with atmospheric models typically characterize landscapes in terms of generalized biome types. However, the advent of high?spatial resolution satellite-derived data products such as land cover ... -
Simulations of the Summer Hydrometeorological Processes of Lake Kinneret
(American Meteorological Society, 2000)Lake Kinneret is a 168-km2 lake located in northern Israel. It provides about 50% of the drinking water consumed in this arid country. To manage correctly this vital water resource, it is essential to understand the various ... -
Assessment of the Use of Lightning Information in Satellite Infrared Rainfall Estimation
(American Meteorological Society, 2000)In this paper, the combined use of cloud-to-ground lightning and satellite infrared (IR) data for rainfall estimation is investigated. Based on analysis of the correlation between satellite microwave and IR rainfall estimates ... -
Using a Soil Hydrology Model to Obtain Regionally Averaged Soil Moisture Values
(American Meteorological Society, 2000)The Soil Hydrology Model (SHM) was modified, and daily simulations of soil volumetric water content were made at 38 Oklahoma Mesonet sites for July 1997. These model results were compared with soil moisture observations ... -
Derived Distributions of Storm Depth and Frequency Conditioned on Monthly Total Precipitation: Adding Value to Historical and Satellite-Derived Estimates of Monthly Precipitation
(American Meteorological Society, 2000)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 ... -
Estimating Watershed Evapotranspiration with PASS. Part I: Inferring Root-Zone Moisture Conditions Using Satellite Data
(American Meteorological Society, 2000)A model framework for parameterized subgrid-scale surface fluxes (PASS) has been modified and applied as PASS1 to use satellite data, models, and limited surface observations to infer root-zone available moisture (RAM) ... -
Real-Time Adjustment of Range-Dependent Biases in WSR-88D Rainfall Estimates due to Nonuniform Vertical Profile of Reflectivity
(American Meteorological Society, 2000)A procedure for real-time adjustment of range-dependent biases in Weather Surveillance Radar-1988 Doppler version (WSR-88D) rainfall estimates due to nonuniform vertical profile of reflectivity is proposed. Using volume-scan ... -
The Impact of Observed Deforestation on the Mesoscale Distribution of Rainfall and Clouds in Amazonia
(American Meteorological Society, 2000)A numerical mesoscale model has been used to investigate the impact of mesoscale circulations on the distribution of precipitation and cloudiness over a deforested area in Amazonia. Observed patterns of deforestation in ... -
A Hybrid Orographic plus Statistical Model for Downscaling Daily Precipitation in Northern California
(American Meteorological Society, 2000)A hybrid (physical?statistical) scheme is developed to resolve the finescale distribution of daily precipitation over complex terrain. The scheme generates precipitation by combining information from the upper-air conditions ... -
From Near-Surface to Root-Zone Soil Moisture Using Year-Round Data
(American Meteorological Society, 2000)Passive microwave remote sensing may provide quantitative information about the water content of a shallow near-surface soil layer. However, the variable of interest for applications such as short- and medium-term ... -
Idealized Model for Equilibrium Boundary Layer over Land
(American Meteorological Society, 2000)An idealized equilibrium mixed layer (ML) model is used to explore the coupling between the surface, the ML, and the atmosphere above. It shows that ML depth increases as vegetative resistance to evaporation increases. The ... -
Global Characteristics of Stream Flow Seasonality and Variability
(American Meteorological Society, 2000)Monthly stream flow series from 1345 sites around the world are used to characterize geographic differences in the seasonality and year-to-year variability of stream flow. Stream flow seasonality varies regionally, depending ... -
A Spatial Model for Soil–Atmosphere Interaction: Model Construction and Linear Stability Analysis
(American Meteorological Society, 2000)A simple model is developed to investigate the role of spatial dynamics in the soil?atmosphere system. The model is constructed by considering the mass and energy balance equations for soil and atmosphere, closed with a ... -
Hydrological Budgets and Surface Energy Balance of Seven Subbasins of the Mackenzie River from the ECMWF Model
