Dynamics of Eddy-Driven Low-Frequency Dipole Modes. Part I: A Simple Model of North Atlantic Oscillations
(American Meteorological Society, 2007-01)
A simple theoretical model is proposed to clarify how synoptic-scale waves drive the life cycle of the North Atlantic Oscillation (NAO) with a period of nearly two weeks. This model is able to elucidate what
determines ...
Calculated Height Tendencies in Two Southern Hemisphere Blocking and Cyclone Events: The Contribution of Diabatic Heating to Block Intensification
(American Meteorological Society, 2008-09)
The Zwack-Okossi vorticity tendency equation was used to calculate 500-hPa height tendencies in two intensifying Southern Hemisphere blocking events. The National Centers for Environmental Prediction-
National Center for ...
Dynamics of Eddy-Driven Low-Frequency Dipole Modes. Part II: Free Mode Characteristics of NAO and Diagnostic Study
(American Meteorological Society, 2007-01)
Through calculating the scatter diagrams of the streamfunction ( P or T) versus potential vorticity (PV)(qP or qT), where P and T are the planetary-scale streamfunction and total streamfunction, respectively, and using ...
Automated Processing of High Resolution Satellite Imagery for Feature Extraction and Mapping of Urban Areas
(EOM Earth Observation Magazine, 2005-01)
High-resolution satellite imagery became commercially available in late 1999 with the launch of Space Imaging's IKONOS satellite. In subsequent years, several other high-resolution commercial satellites were launched ...
How beneficial are thiazolidinediones for diabetes mellitus?
(Family Physicians Inquiries Network, 2002)
The thiazolidinediones pioglitazone (Actos) and rosiglitazone (Avandia) are effective at lowering fasting plasma glucose (FPG) and glycosylated hemoglobin (Hb A1c) in patients with type 2 diabetes when used either as ...
Do antioxidants (vitamins C, E) improve outcomes in patients with coronary artery disease?
(Family Physicians Inquiries Network, 2002)
Antioxidant supplements of vitamins E and C do not reduce cardiovascular death in people with coronary artery disease. Vitamin E supplementation, in a variety of doses, does not decrease the incidence of cardiovascular or ...
How effective are exercise and physical therapy for chronic low back pain?
(Family Physicians Inquiries Network, 2002)
Exercise is more effective for chronic low back pain than treatment with medication plus return to usual activity and as effective as conventional physiotherapy. The evidence is less consistent in showing that any particular ...
Does postcoital voiding prevent urinary tract infections in young women?
(Family Physicians Inquiries Network, 2002)
Healthy women who urinate within 15 minutes of sexual intercourse may be slightly less likely to develop a urinary tract infection (UTI) than women who do not urinate afterward (grade of recommendation: D, extrapolation ...
A comparison of two cases of low-latitude thundersnow
(Centro Ciencias Atmosfera UNAM, 2009-03)
Two cases of low-latitude snow with lightning are studied to determine their characteristics. Both cases had synoptic-scale origins, but also featured smaller-scale influences (e. g. orographic lift and elevated instability).The ...
ACMES: fast multiple-genome searches for short repeat sequences with concurrent cross-species information retrieval
(Nucleic Acids Research, 2004)
We have developed a web server for the life sciences community to use to search for short repeats of DNA sequence of length between 3 and 10 000 bases within multiple species. This search employs a unique
and fast hash ...
South American Cold Surges: Types, Composites, and Case Studies
(American Meteorological Society, 2001-05)
This paper examines the climatological, large-scale, and synoptic-scale aspects of South American cold surges using NCEP-NCAR gridded reanalyses for the 1992-96 period. Three common cold surge types are identified on the ...
A Diagnosis of the Explosive Development of Two Extratropical Cyclones
(American Meteorological Society, 1992-08)
This paper examines the 24-h explosive development periods of two extratropical cyclones, the first occurring over the Gulf Stream off the coast of New England from 18 to 19 January 1979 and the second occurring over the ...
The Status of Underage Drinking and Laws in Missouri
(University of Missouri - Columbia Institute of Public Policy, 2004)
Underage drinking presents a serious public health problem in the United States with 10.7
million youth ages 12-20 reporting consumption of alcohol. Twenty-eight percent of youth ages 12-20 report using alcohol within the ...
Interannual and interdecadal variability in the predominant Pacific region SST anomaly patterns and their impact on climate in the mid-Mississippi valley region
(Centro Ciencias Atmosfera UNAM, 2007-02)
Previous research has demonstrated that Pacific Region SSTs and SST anomalies can be separated into seven general synoptic classifications (“clusters”) (A-G). Clusters B and G (C, D, and F) [A and E] were shown to be ...
Using the monthly classification of global SSTs and 500 HPA height to predict temperature and precipitation regimes one to two season in advance for the Mid-Mississippi Region
(National Weather Association, 2008-07)
Using the results from previous studies of the interannual variability of local mean monthly temperature and precipitation by this group, long range forecasts were generated for summer and winter season temperatures and ...
The Interannual variability of hurricane activity in the Atlantic and east pacific regions
(National Weather Association, 2008-07)
The investigation of the interannual and interdecadal variations in hurricane activity has been an important topic of study lately, especially with regard to their implications for climate change issues. On the interannual ...
