Realtime Analysis and Forecasting with ARPS
Operational Analysis and Forecasting with ARPS
CAPS has served the meteorological community since 1997 by continuously
providing real-time numerical analyses and forecasts. CAPS realtime high-resolution
weather analyses and forecasts throughout the year can be accessed
through the CAPS/wx system.
Realtime Analysis with ADAS at University of Oklahoma
ARPS Data Analysis System (ADAS)
is being run daily to produce hourly
analysis for the southern great plain. This is an effort by Keith Brewster
in parallel to the CAPS real time analysis
and forecast operation.
of Utah Realtime ADAS Analysis
is being done with ADAS at the Department of Meteorology,
University of Utah. It is part of the
Utah Mesonet Project.
State University ARPS Real time forecast
Once each day, ARPS is run for a region encompassing Western Oregon and
much of the Pacific Northwest. This modeling effort is the result of cooperation
from several departments at Oregon State University including the College
of Oceanic and Atmospheric Sciences (COAS) and the Department of Mechanical
ARPS is being used to produce regional forecasts at Galicia region of northwest Spain.
Hongkong Observoatory is also doing experiment forecast using ARPS
in Hongkong area.
Testing of ARPS in Korean Environment (TAKE)
ARPS is being tested at Korean Meteorological
Agency (KMA) since 1997, mostly during the Changma (Meiyu) seasons
(July - August). A conference
paper summarizes the efforts in 1997.
Operationalization of ARPS model for
commonwealth games 2010 at India Meteorological Department
ARPS will be run initially during 07-12 UTC every day at NWP center,
India Meteorological Department, New Delhi, India for commonwealth
games 2010 to be held in DELHI during 03-13 Oct. 2010. Products
will be avaialbe at http://www.imd.gov.in/section/nhac/dynamic/arps.htm.
Past Real Time Forecast Projects at CAPS
Project Hub-CAPS (see Carpenter,
et al., 1999), a 3-year research and development partnership between
American Airlines and the University of Oklahoma to adapt storm-scale numerical
weather prediction technology for commercial airline operations. This project
has now been merged with the regular CAPS real time forecast effort.
A multi-institutional NWP experiment during spring, 1998 convective
season over the central US. Known as SAMEX '98 (Storm and Mesoscale Ensemble
Experiment, spring 1998), this effort involves a realtime comparison of
approximately 30 ensemble forecasts, run at 30 km resolution using 3 models,
against forecasts run at both intermediate (10 km) and high (2-3 km) resolution
over sub-sets of the ensemble domain.
CAPS SAMEX'98 Forecast Experiment
ARPS was run at part of SAMEX'98
during May 1998, at 27/9 km resolutions,
on PSC's massively parallel Cray T3E, using 128 processors. The forecast products
are at http://origin.caps.ou.edu/~samex/arps/.
forecasting experiment during VORTEX'95
The ARPS model is being run daily through June 1995 in
support of the VORTEX
project. Participants in this evaluation include the NOAA NSSL, the Norman
NWSFO, the NOAA SPC, and
the OU School of Meteorology. Forecasting
results are summarized in Droegemeier
et al (1996a) and Xue
et al (1996a).
operational period during 1996 (SOP96)
The 1996 CAPS Spring Operational Storm-Scale Prediction
Experiment is a collaborative effort among OU's
CAPS, the Norman NWSFO ,
the NOAA SPC, and the National
Aviation Weather Center (AWC). The principal goal is to conduct high-resolution,
short-term numerical predictions of convective weather on a daily basis,
and to evaluate the quality of these forecasts in operational settings.
Forecasting results are summarized in Droegemeier
et al (1996b) and Xue
et al (1996b).
The goal of the COMET-Tinker Project is to evaluate the forecasting
effectiveness of the ARPS mesoscale model by Air Force weather personnel.
This project is a cooperative effort between the School of Meteorology (SOM),
at the University of Oklahoma, and the 72nd Air Base Wing Weather Flight
at Tinker Air Force Base, Oklahoma. The project is funded by the COoperative
Program for Operational Meteorology, Education and Training (COMET)
Outreach Program of the University Corporation for Atmospheric Research
(UCAR) and by the Air Weather Service (AWS) of the United States Air Force.
