RISWeather and Forecasting Challenges in the Pacific Region of the National Weather Service
Publisher: American Meteorological Society
Abstract: The large area of responsibility covered by the Pacific Region of the National Weather Service provides a unique set of challenges to operational forecasters. Extratropical, subtropical, and tropical meteorological phenomena ...
Heavy Rain Events over the South-Facing Slopes of Hawaii: Attendant Conditions
Publisher: American Meteorological Society
Abstract: Heavy rain events (>100 mm day?1) over the southeast flank of Mauna Loa volcano on the island of Hawaii are examined using surface, rawinsonde, rain gauge, and satellite data. The events occur in the presence of four types ...
Validation of the Coupled NCEP Mesoscale Spectral Model and an Advanced Land Surface Model over the Hawaiian Islands. Part II: A High Wind Event
Publisher: American Meteorological Society
Abstract: A high wind event (14?15 February 2001) over the Hawaiian Islands associated with a cold front is simulated using the National Centers for Environmental Prediction (NCEP) Mesoscale Spectral Model (MSM) coupled with an ...
Numerical Simulations of Sea-Breeze Circulations over Northwest Hawaii
Publisher: American Meteorological Society
Abstract: Sea-breeze cases during 23?28 June 1978 over northwest Hawaii are simulated using the National Centers for Environmental Prediction (NCEP) Mesoscale Spectral Model (MSM) coupled with an advanced Land Surface Model (LSM) ...
A Comparison of Three Prolonged Periods of Heavy Rainfall over the Hawaiian Islands
Publisher: American Meteorological Society
Abstract: he anomalous circulation patterns during an unusually prolonged stormy-weather period in Hawaii from 19 February to 2 April 2006 are analyzed and are compared with those of two previously known prolonged heavy-rainfall ...
Application of the NCEP Regional Spectral Model to Improve Mesoscale Weather Forecasts in Hawaii
Publisher: American Meteorological Society
Abstract: The operational implementation of the National Centers for Environmental Prediction (NCEP) Regional Spectral Model (RSM) in Hawaii is the first application of a mesoscale model to improve weather forecasts in the Pacific ...
A Bow Echo and Severe Weather Associated with a Kona Low in Hawaii
Publisher: American Meteorological Society
Abstract: On 2 November 1995 a kona low formed to the northwest of Hawaii. During the following 48 h a series of convective rainbands developed on the southeastern side of the low as it slowly moved eastward. On the afternoon of 3 ...
Validation of the Coupled NCEP Mesoscale Spectral Model and an Advanced Land Surface Model over the Hawaiian Islands. Part I: Summer Trade Wind Conditions and a Heavy Rainfall Event
Publisher: American Meteorological Society
Abstract: Validations of the 10-km operational Regional Spectral Model (RSM) and the coupled Mesoscale Spectral Model (MSM) with an advanced land surface model (LSM) forecasts during a 1-month period from 20 May through 20 June 2002 ...
Variability of Hawaiian Winter Rainfall during La Niña Events since 1956
Publisher: American Meteorological Society
Abstract: ainfall in Hawaii during La Niña years has undergone abnormal variability since the early 1980s. Traditionally, Hawaii receives greater-than-normal precipitation during the La Niña wet seasons. Recently, La Niña years have ...
Applying Horizontal Diffusion on Pressure Surface to Mesoscale Models on Terrain-Following Coordinates
Publisher: American Meteorological Society
Abstract: The National Centers for Environmental Prediction regional spectral model and mesoscale spectral model (NCEP RSM/MSM) use a spectral computation on perturbation. The perturbation is defined as a deviation between RSM/MSM ...
