Evaluation of the Summertime Low-Level Winds Simulated by MM5 in the Central Valley of California

Source: Journal of Applied Meteorology and Climatology:;2010:;volume( 049 ):;issue: 011:;page 2230

Author(s): Michelson, Sara A.; Djalalova, Irina V.; Bao, Jian-Wen

Publisher: American Meteorological Society

Abstract: A season-long set of 5-day simulations between 1200 UTC 1 June and 1200 UTC 30 September 2000 are evaluated using the observations taken during the Central California Ozone Study (CCOS) 2000 experiment. The simulations are ...

Snowfall Retrievals Using Millimeter-Wavelength Cloud Radars

Source: Journal of Applied Meteorology and Climatology:;2008:;volume( 047 ):;issue: 003:;page 769

Author(s): Matrosov, Sergey Y.; Shupe, Matthew D.; Djalalova, Irina V.

Publisher: American Meteorological Society

Abstract: It is demonstrated that millimeter-wavelength radars that are designed primarily for cloud studies can be also used effectively for snowfall retrievals. Radar reflectivity?liquid equivalent snowfall rate (Ze?S) relations ...

Inferring Fall Attitudes of Pristine Dendritic Crystals from Polarimetric Radar Data

Source: Journal of the Atmospheric Sciences:;2005:;Volume( 062 ):;issue: 001:;page 241

Author(s): Matrosov, Sergey Y.; Reinking, Roger F.; Djalalova, Irina V.

Publisher: American Meteorological Society

Abstract: Single pristine planar ice crystals exhibit some flutter around their preferential horizontal orientation as they fall. This study presents estimates of flutter and analyzes predominant fall attitudes of pristine dendritic ...

A Wind Energy Ramp Tool and Metric for Measuring the Skill of Numerical Weather Prediction Models

Source: Weather and Forecasting:;2016:;volume( 031 ):;issue: 004:;page 1137

Author(s): Bianco, Laura; Djalalova, Irina V.; Wilczak, James M.; Cline, Joel; Calvert, Stan; Konopleva-Akish, Elena; Finley, Cathy; Freedman, Jeffrey

Publisher: American Meteorological Society

Abstract: wind energy Ramp Tool and Metric (RT&M) has been developed out of recognition that during significant ramp events (large changes in wind power over short periods of time ) it is more difficult to balance the electric load ...

The POWER Experiment: Impact of Assimilation of a Network of Coastal Wind Profiling Radars on Simulating Offshore Winds in and above the Wind Turbine Layer

Source: Weather and Forecasting:;2016:;volume( 031 ):;issue: 004:;page 1071

Author(s): Djalalova, Irina V.; Olson, Joseph; Carley, Jacob R.; Bianco, Laura; Wilczak, James M.; Pichugina, Yelena; Banta, Robert; Marquis, Melinda; Cline, Joel

Publisher: American Meteorological Society

Abstract: uring the summer of 2004 a network of 11 wind profiling radars (WPRs) was deployed in New England as part of the New England Air Quality Study (NEAQS). Observations from this dataset are used to determine their impact on ...

Evaluating and Improving NWP Forecast Models for the Future: How the Needs of Offshore Wind Energy Can Point the Way

Source: Bulletin of the American Meteorological Society:;2017:;volume 099:;issue 006:;page 1155

Author(s): Banta, Robert M.; Pichugina, Yelena L.; Brewer, W. Alan; James, Eric P.; Olson, Joseph B.; Benjamin, Stanley G.; Carley, Jacob R.; Bianco, Laura; Djalalova, Irina V.; Wilczak, James M.; Hardesty, R. Michael; Cline, Joel; Marquis, Melinda C.

Publisher: American Meteorological Society

Abstract: AbstractTo advance the understanding of meteorological processes in offshore coastal regions, the spatial variability of wind profiles must be characterized and uncertainties (errors) in NWP model wind forecasts quantified. ...
