Cloud and Precipitation Parameterizations in Modeling and Variational Data Assimilation: A Review
(American Meteorological Society, 2007)This paper first reviews the current status, issues, and limitations of the parameterizations of atmospheric large-scale and convective moist processes that are used in numerical weather prediction and climate general ... -
Issues Regarding the Assimilation of Cloud and Precipitation Data
(American Meteorological Society, 2007)The assimilation of observations indicative of quantitative cloud and precipitation characteristics is desirable for improving weather forecasts. For many fundamental reasons, it is a more difficult problem than the ... -
The Intense Lee-Wave Rotor Event of Sierra Rotors IOP 8
(American Meteorological Society, 2007)A large-amplitude lee-wave rotor event observationally documented during Sierra Rotors Project Intensive Observing Period (IOP) 8 on 24?26 March 2004 in the lee of the southern Sierra Nevada is examined. Mountain waves and ... -
Assimilation of Precipitation Information Using Column Model Physics as a Weak Constraint
(American Meteorological Society, 2007)Currently, operational weather forecasting systems use observations to optimize the initial state of a forecast without considering possible model deficiencies. For precipitation assimilation, this could be an issue since ... -
Millimeter-Wave Precipitation Retrievals and Observed-versus-Simulated Radiance Distributions: Sensitivity to Assumptions
(American Meteorological Society, 2007)Brightness temperature histograms observed at 50?191 GHz by the Advanced Microwave Sounding Unit (AMSU) on operational NOAA satellites are shown to be consistent with predictions made using a mesoscale NWP model [the ... -
On the Combined Effects of Turbulence and Gravity on Droplet Collisions in Clouds: A Numerical Study
(American Meteorological Society, 2009)This paper examines the combined influences of turbulence and gravity on droplet collision statistics in turbulent clouds by means of direct numerical simulation (DNS). The essential microphysical mechanisms that determine ... -
A Barotropic Envelope Rossby Soliton Model for Block–Eddy Interaction. Part I: Effect of Topography
(American Meteorological Society, 2005)A new forced envelope Rossby soliton model in an equivalent barotropic beta-plane channel is proposed to describe the interaction between an incipient block (planetary scale) and short synoptic-scale eddies. This model is ... -

Tropical Upper-Tropospheric Extended Clouds: Inferences from Winter MONEX
(American Meteorological Society, 1980)The most common cloud species observed during the Winter Monsoon Experiment (WMONEX) wasthick (optically black) middle and upper tropospheric extended cloud. Data from the GeostationaryMeteorological Satellite (GMS) showed ... -

Approximation of Single Scattering Properties of Ice and Snow Particles for High Microwave Frequencies
(American Meteorological Society, 2004)As satellite high-frequency passive microwave data have recently become available, there is an increasing demand for an accurate and computationally efficient method to calculate the single scattering properties of ... -

Can Anthropogenic Aerosols Decrease the Snowfall Rate?
(American Meteorological Society, 2004)Observations by Borys, Lowenthal, Cohn, and Brown in midlatitude orographic clouds show that for a given supercooled liquid water content, both the riming and the snowfall rates are smaller if the supercooled cloud has ... -
Retrieval of Atmospheric Optical Depth Profiles from Downward-Looking High-Resolution O2 A-Band Measurements: Optically Thin Conditions
(American Meteorological Society, 2004)A quasi-linear retrieval was developed to profile moderately thin atmospheres using a high-resolution O2 A-band spectrometer. The retrieval is explicitly linear with respect to single scattering; the multiple-scattering ... -
Derivation of the Equations of Atmospheric Motion in Oblate Spheroidal Coordinates
(American Meteorological Society, 2004)Since Earth is more nearly an oblate spheroid than a sphere, it is of at least theoretical interest to develop the atmospheric equations of motion in spheroidal coordinates. In this system the horizontal unit vectors are ... -
Predictability and Information Theory. Part I: Measures of Predictability
(American Meteorological Society, 2004)This paper gives an introduction to the connection between predictability and information theory, and derives new connections between these concepts. A system is said to be unpredictable if the forecast distribution, which ... -
