An analysis of a long-lived MCV observed over the Southern Plains using Potential Vorticity diagnostics.
(National Weather Association, 2000-09)
On the morning of 28 May 1998, a mesoscale convectively-generated vortex (MCV) was
observed over the Southern Plains. This MCV was evident in the GOES-8 visual satellite
imagery resulting in a spectacular picture. An ...
An Analysis of a Relatively Rare Case of Continental Blocking
(Jon Wiley and Sons, 1999-01)
A planetary and synoptic-scale analysis of a relatively rare continental blocking event that occurred over North America during the spring of 1980 are undertaken to determine whether or not this event was different from ...
A Diagnosis of Two Blocking Events That Occurred Simultaneously in the Midlatitude Northern Hemisphere
(American Meteorological Society, 1997-08)
Using the Goddard Laboratory for Atmospheres Goddard Earth Observing System-1 analyses, the horizontal distribution of atmospheric forcing processes involved in the growth, maintenance, and decay of two Northern
Hemisphere ...
The Interactions between a Midlatitude Blocking Anticyclone and Synoptic-Scale Cyclones That Occurred during the Summer Season
(American Meteorological Society, 1998-02)
Using the Goddard Laboratory for Atmospheres Goddard Earth Observing System 5-yr analysis and the Zwack-Okossi equation as the diagnostic tool, the horizontal distribution of the dynamic and thermodynamic forcing processes ...
Assessment of the Impact of the Planetary Scale on the Decay of Blocking and the Use of Phase Diagrams and Enstrophy as a Diagnostic
(Pleiades Publishing, 2007-01)
It was shown that abrupt changes in the large-scale structure of atmospheric flows may lead to the rapid decay of blocking. Analysis of phase diagrams made it possible to identify when sharp changes occurred in the dynamics ...
A Climatology of Northern Hemisphere Blocking
(American Meteorological Society, 2006-03)
In this paper a 55-yr (1948-2002) Northern Hemisphere blocking climatology is presented. Traditional blocking indices and methodologies are revised and a new blocking detection method is designed. This algorithm detects ...
Analysis of Weather Data Collected From Two Locations in a Small Urban Community
(Missouri Academy of Science, 2006-01)
The heat island effect is a well known feature in the microclimate of urban areas, and is considered to be the difference between the urban area and its surroundings. While this study only employs two instruments, 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 ...
Planetary and synoptic-scale interactions during the life cycle of a mid-latitude blocking anticyclone over the North Atlantic
(Munksgaard, 1995-10)
The formation of a blocking anticyclone over the North Atlantic has been examined over its entire life-cycle using the Zwack-Okossi (Z-O) equation as the diagnostic tool. This blocking anticyclone occurred in late October ...
A Diagnosis of the development of a Winter Anticyclone over North America
(American Meteorological Society, 1995-08)
This paper examines the 48-h life cycle of a winter anticyclone occurring over North America from 18 to 20 January 1979 using Goddard Laboratory for Atmospheres FGGE level IIIb (SOP 1) global analyses on a 4° latitude by ...
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) ...
Interannual Variability of Snowfall Events Southwest Missouri and Snowfall to- Liquid Water Equivalents at the Springfield WFO
(National Weather Association, 2005-12)
In order to address the difficult issue of forecasting snowfall amounts for the general
public, forecasters must be intimately familiar with the climatological behavior of snowfall events, and associated snowfall-to-liquid ...
The diagnosis of a pre-blocking explosively-developing extratropical cyclone system
(Munksgaard, 1992-05)
This paper presents the diagnosis of an extratropical cyclone that developed explosively from 18 to 19 January 1979 over the North Atlantic Ocean. The diagnosis applies data obtained from the Goddard Laboratory for Atmospheres ...
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 Diagnosis of the Explosive Development of Two Extratropical Cyclones
(American Meteorological Society, 1992-08)
