A synoptic climatology for environmental baseline analysis: New Orleans
Huit types de circulation atmosphérique sont identifiés à la Nouvelle-Orléans à partir des cartes quotidiennes de surface. Les types de temps associés sont étudiés. (DY).
Modes of synoptic development within the Polar Basin
The patterns of advective development are classified for twelve synoptic sequences in the Polar Basin during the June through October interval of 1979. The intent is to develop models of the advective contribution to synoptic evolution.
Synoptic weather types : an index of evaporation in southern Louisiana
Synoptic weather types have been found to be useful tools in the study of various environmental processes. One viable use of synoptic weather types is the determination of regional estimates of evaporation. In southern Louisiana, rates of mean daily
pan evaporation by synoptic weather types are useful as an index of evaporation, based on the frequency of weather type occurrence.
This paper analyzes summer, 1986, daily surface energy budgets, ablation, and variations of synoptic weather types experienced on the West Gulkana Glacier. Daily summer (June-August) synoptic conditions analyzed for the period 1948-86 were
undertaken to interpret possible long-term changes in ablation. The synoptic conditions that enhance ablation have significantly increased over the period 1957 to the present.

Synoptic climatology is defined as the study of climates from the viewpoint of their atmospheric circulation components and emphasizes the connection between circulation, weather phenomena, and climatic differentiation. The field is seen as having
Synoptic climatology of the daily 700mb summer monsoon flow patterns over India
Les cartes synoptiques journalières se rapportant au niveau isobarique 700mb sont classées en cinq grands types pour chaque mois d'été (juin-septembre). Pour chaque type de circulation ainsi reconnu, les AA. évaluent la probabilité des
Using a spatial synoptic climatological classification to assess changes in atmospheric pollution concentrations
The goal of this research is to demonstrate the potential of a newly developed spatial synoptic climatological classification to assess changes in atmospheric pollution concentrations in nine U.S. cities. The procedure divides the United States
into homogeneous regions on the basis of surface synoptic weather data. The resulting categories are then related to metropolitan-scale pollution concentrations. Thus, it becomes possible to determine the characteristics of those synoptic situations associated
Synthèse modèle conçue en deux parties : une première partie avec 5 chapitres sur l'organisation et la réalisation des observations, la transmission des données enregistrées pour la réalisation des cartes synoptiques, et une deuxième partie avec les

Analyse succinte appuyée sur trois cartes météorologiques d'une tempête de neige tout à fait mémorable qui rappelle celle des 9 et 10 novembre 1876. Ces deux évènements sont caractérisés par leur précocité (en novembre) et par les pressions très
Synoptic and surface climatology interactions in the Central Canadian Subarctic : normal and El Niño seasons
Canada ; Classification ; Cold area ; El Niño ; Evaporation ; Precipitation ; Seasonal variation ; Snow ; Subarctic zone ; Synoptic climatology ; Thematic mapping ; Vegetation dynamics ; Weather type ; Years 1990-99
An objective hybrid classification of daily surface weather maps for Churchill, Manitoba, was used to determine the dominant synoptic conditions during the snowmelt and snow-free periods for the Canadian central subarctic. This classification
yielded different dominant synoptic types for the two normal (1996, 1997) and one El Niño (EN), (1998), seasons. The synoptic patterns that emerged were then related to the precipitation and surface evaporation regimes of a subarctic sedge fen typical
A synoptic climatology of northeastern United States tornadoes
This paper represents an attempt to understand better the characteristics of tornadic events and the synoptic scale patterns associated with their initiation. The information presented here concerning the temporal and spatial nature of tornadic
Synoptic-scale variability in the probability of precipitation from thunderstorms in the United States
A synoptic-scale climatology of precipitation amounts from thunderstorms is developed by analysis of amounts from individual storms for 220 stations in the conterminous United States for the period 1948-1977. The probability of having a thunderstorm
Synoptical conditions and their influence on the formation of high waves along the rivers Varbitza and Yantra
This work elucidates the formation and specific features of high waves in two river basins in different climatic zones of Bulgaria. The typization of the synoptic material was made on the basis of 283 characteristic precipitation situations. - (SBV)
A synoptic weather type analysis of january hourly precipitation at Lake Charles, Louisiana
Each measurable hourly precipitation event during january at Lake Charles, over the 1951-80 period has been classified by associated synoptic weather type. Using Muller's synoptic classification, four types were found to produce rainfall over
A synoptic climatology of cool-season derecho events
This paper examines synoptic environments associated with cool-season derechos, 1986 to 1995, those events occurring between September and February. Commonalities within the synoptic environments of these events are identified and illustrated
