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 ...
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 ...
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 ...
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 ...
Interannual variability of tropical cyclone activity in the southern South China Sea
(American Geophysical Union, 2008-03)
A study of tropical storm activity in the southern South China Sea region was carried
out for the period of 1960 to 2006 using data obtained from the UNISYS website archive, which was provided to them from the Joint Typhoon ...
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 ...
The Climatology of Blocking Anticyclones for the Northern and Southern Hemispheres: Block Intensity as a Diagnostic
(American Meteorological Society, 2002-12)
A 30-yr climatology of blocking events was compiled by stratifying the data into seasonal and three regional categories for both the Northern and Southern Hemispheres using the NCEP-NCAR reanalyses. Several characteristics ...
The Presentation of Precipitation Information in Television Broadcasts: What is Normal?
(2008)
In a typical weather broadcast, observed precipitation information such as the daily amount that fell and the accumulated monthly total are shown and compared to the mean monthly average or “normal” precipitation. Such ...
The Presentation of Temperature Information in Television Broadcasts: What is Normal?
(National Weather Association, 2003-12)
In a typical weather broadcast, observed daily temperature information such as maximum
and minimum temperatures are shown and compared to the daily average or “normal”. Such information, however, does not accurately ...
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 ...
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 Climatology of Northwest Missouri Snowfall Events: Long Term Trends and Interannual Variability.
(V. H. Winston and Son Inc., 2003-01)
The goal of this study was to develop a 50-year statistical climatology of snowfall
occurrences using data from a dense network of cooperative station observations covering
northwest and central Missouri, and these records ...
The Short and Long-term Variability of F2 or Stronger (Significant) Tornadoes in the Central Plains
(Missouri Academy of Science, 2004-08)
An analysis of the interannual and interdecadal variability of significant tornado events that occurred over a four state region in the central plains was performed over a 53 year period (1950 - 2002) using the Storm ...
Further studies of the heat island associated with a small midwestern city
(Royal Meteorological Society, 2008-09)
Recently, the University of Missouri (UM) moved its SuomiNet station from the roof
of a building near downtown Columbia, Missouri, USA, to the University's rural South Farm. Comparisons of Columbia Regional Airport (KCOU) ...
The Planetary- and Synoptic-Scale Interactions in a Southeast Pacific Blocking Episode Using PV Diagnostics
(American Meteorological Society, 2005-06)
The synoptic- and planetary-scale forcing in two blocking anticyclones occurring over the southeast Pacific Ocean was examined using potential vorticity diagnostics. While many studies have examined the dynamic and ...
Ageostrophic Forcing in a Height Tendency Equation
