RISCloud-to-Ground Lightning Flash Parameters Associated with Heavy Rainfall Alarms in the Denver, Colorado, Urban Drainage and Flood Control District ALERT Network
Publisher: American Meteorological Society
Abstract: Rainfall data from the Denver, Colorado, Urban Drainage and Flood Control District Automated Local Evaluation in Real Time (ALERT) network were used to identify heavy rainfall alarms for the period 1999?2003. Twenty-nine ...
Patterns of Cloud-to-Ground Lightning and Convective Rainfall Associated with Postwildfire Flash Floods and Debris Flows in Complex Terrain of the Western United States
Publisher: American Meteorological Society
Abstract: Flash flood and debris flow reports from Storm Data and the U.S. Geological Survey (USGS) are used to investigate the relationship between hazardous hydrological responses, convective rainfall, and cloud-to-ground (CG) ...
A Method to Identify the Optimal Areal Unit for NLDN Cloud-to-Ground Lightning Flash Data Analysis
Publisher: American Meteorological Society
Abstract: Currently, no uniform method exists for determining the optimal areal unit to analyze National Lightning Detection Network (NLDN) data. To address this problem, this paper utilizes the capabilities of modern geographic ...
The Role of Upstream Midtropospheric Circulations in the Sierra Nevada Enabling Leeside (Spillover) Precipitation. Part I: A Synoptic-Scale Analysis of Spillover Precipitation and Flooding in a Leeside Basin
Publisher: American Meteorological Society
Abstract: Pacific-originating storms that produce heavy leeside liquid precipitation in the Sierra Nevada are rare compared to those that generate windward slope rainfall. However, these leeside precipitation events have a profound ...
A Multiple-Case Analysis of Nocturnal Radiation-Fog Development in the Central Valley of California Utilizing the GOES Nighttime Fog Product
Publisher: American Meteorological Society
Abstract: Radiation fog in the Central Valley of California has received very little attention in terms of climatological research. This study uses the Geostationary Operational Environmental Satellite (GOES) nighttime fog product ...
Synoptic Climatological Analyses of Extreme Snowfalls in the Sierra Nevada
Publisher: American Meteorological Society
Abstract: The Sierra Nevada of eastern California receives heavy snowfall each year. However, it is the snowstorms that deposit heavy snowfall in a relatively short period of time that can cause major inconveniences and even ...
Synoptic-Scale Features Common to Heavy Snowstorms in the Southeast United States
Publisher: American Meteorological Society
Abstract: Eighteen heavy snowstorms in the Southeast are examined to determine the synoptic-scale features common to these storms. Storm-relative composites in the temporal domain are created by assigning a ?zero hour? to each storm ...
The Role of Upstream Midtropospheric Circulations in the Sierra Nevada Enabling Leeside (Spillover) Precipitation. Part II: A Secondary Atmospheric River Accompanying a Midlevel Jet
Publisher: American Meteorological Society
Abstract: The synoptic structure of two case studies of heavy ?spillover? or leeside precipitation?1?2 January 1997 and 30?31 December 2005?that resulted in Truckee River flooding are analyzed over the North Pacific beginning ...
