Reconstruction of Near-Surface Tornado Wind Fields from Forest Damage
(American Meteorological Society, 2010)Tornado intensity is usually inferred from the damage produced. To foster postevent tornado intensity assessments, the authors present a model to reconstruct near-surface wind fields from forest damage patterns. By comparing ... -
Boundary Conditions for Artificial Snow Production in the Austrian Alps
(American Meteorological Society, 2010)To assess how meteorological conditions favorable for the production of artificial snow vary in time and space, wet-bulb temperatures are calculated using temperature and humidity data of 14 Austrian stations between October ... -
Foehn-Like Winds and Elevated Fire Danger Conditions in Southeastern Australia
(American Meteorological Society, 2010)Bushfires in southeastern Australia are a serious environmental problem, and consistently cause loss of life and damage to property and other assets. Understanding synoptic processes that can lead to dangerous fire weather ... -
An Empirical Latent Heat Flux Parameterization for the Noah Land Surface Model
(American Meteorological Society, 2010)Proper partitioning of the surface energy fluxes that drive the evolution of the planetary boundary layer in numerical weather prediction models requires an accurate representation of initial land surface conditions. ... -
Spatial Predictions of Extreme Wind Speeds over Switzerland Using Generalized Additive Models
(American Meteorological Society, 2010)The purpose of this work is to present a methodology aimed at predicting extreme wind speeds over Switzerland. Generalized additive models are used to regionalize wind statistics for Swiss weather stations using a number ... -
Climatology of Velocity and Temperature Turbulence Statistics Determined from Rawinsonde and ACARS/AMDAR Data
(American Meteorological Society, 2010)The climatology of the spatial structure functions of velocity and temperature for various altitudes (pressure levels) and latitude bands is constructed from the global rawinsonde network and from Aircraft Communications, ... -
Cessation of the 22–25 June 2006 Coastally Trapped Wind Reversal
(American Meteorological Society, 2010)Coastally trapped wind reversals (CTWRs) occur periodically in the marine boundary layer off the western coast of the United States and dramatically change the low-level wind regime and coastal weather. Southerly flow ... -
Construction of Digital Elevation Models for a Southern European City and a Comparative Morphological Analysis with Respect to Northern European and North American Cities
(American Meteorological Society, 2010)A morphometric analysis of a southern European city and the derivation of relevant fluid dynamical parameters for use in urban flow and dispersion models are explained in this paper. Calculated parameters are compared with ... -
A Synoptic Weather Typing Approach to Simulate Daily Rainfall and Extremes in Ontario, Canada: Potential for Climate Change Projections
(American Meteorological Society, 2010)An automated synoptic weather typing and stepwise cumulative logit/nonlinear regression analyses were employed to simulate the occurrence and quantity of daily rainfall events. The synoptic weather typing was developed ... -
Improved Estimates of the European Winter Windstorm Climate and the Risk of Reinsurance Loss Using Climate Model Data
(American Meteorological Society, 2010)Current estimates of the European windstorm climate and their associated losses are often hampered by either relatively short, coarse resolution or inhomogeneous datasets. This study tries to overcome some of these ... -
Assessing the Short-Term Forecast Capability of Nonstandardized Surface Observations Using the National Digital Forecast Database (NDFD)
(American Meteorological Society, 2010)The number of surface observations from nonstandardized networks across the United States has appreciably increased the last several years. Automated Weather Services, Inc. (AWS), maintains one example of this type of ... -
Impact of Surface Flux Formulations and Geostrophic Forcing on Large-Eddy Simulations of Diurnal Atmospheric Boundary Layer Flow
(American Meteorological Society, 2010)The impact of surface flux boundary conditions and geostrophic forcing on multiday evolution of flow in the atmospheric boundary layer (ABL) was assessed using large-eddy simulations (LES). The LES investigations included ... -
Urban Modification of Thunderstorms: An Observational Storm Climatology and Model Case Study for the Indianapolis Urban Region
(American Meteorological Society, 2010)radar-based climatology of 91 unique summertime (May 2000?August 2009) thunderstorm cases was examined over the Indianapolis, Indiana, urban area. The study hypothesis is that urban regions alter the intensity and ... -
