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 ...
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 ...
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 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 ...
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 ...
The Application of a Simple Method for the Verification of Weather Forecasts and Seasonal Variations in Forecast Accuracy
(American Meteorological Society, 2002-08)
The evaluation of weather forecast accuracy has always been a difficult subject to address for many reasons. In this study, a simple semiobjective method is used to examine the accuracy of zone forecasts issued by the ...
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 ...
The Wintertime Southern Hemisphere Split Jet: Structure, Variability, and Evolution
(American Meteorological Society, 2001-11)
A persistent feature of the Southern Hemisphere upper-level time-mean flow is the presence of a split jet across the South Pacific east of Australia during the austral winter. The split jet is composed of the subtropical ...
Climatological features of blocking anticyclones: a study of Northern Hemisphere CCM1 model blocking events in present-day and double CO2 concentration atmospheres
(Springer-Verlag, 1997)
Using output made with the National Center
for Atmospheric Research (NCAR) Community Climate Model Version 1 (CCM1), the characteristics of blocking events over the Northern Hemisphere in a ten-year present
day control ...
The Variability in Atlantic Ocean Basin Hurricane Occurrence and Intensity as related to ENSO and the North Pacific Oscillation
(National Weather Association, 2000-06)
The investigation of the effect of El Niño-related variability on hurricane activity has been a popular topic of study. Studies have shown that there are fewer Atlantic Ocean basin hurricanes during an El Nino year than ...
Determining the Spring to Summer Transition in the Missouri Ozarks Using Synoptic Scale Atmospheric Data
(Missouri Academy of Science, 2002-12)
There is abundant anecdotal evidence available to suggest that the transition from a spring to summer season flow regime is often quite abrupt. This same transition renders longrange forecasting problematic as the forecast ...
Climatological Features of blocking anticyclones in the Northern Hemisphere
(Munksgaard, 1994)
Blocking anticyclones have long been of interest to the atmospheric science community because of their profound effect on local and regional climates. Previous climatologies of blocking anticyclones have been performed ...
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 ...
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 ...
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
