SYNOPTIC PATTERNS ASSOCIATED WITH NORTHEAST AND South east ice Storms
… to utility services and disrupt travel. These synoptic systems involve deep isothermal regions where warm, moist air over-runs surface sub-freezing air. Much attention has been focused on Northeast ice storms, where a study by Cortinas et al. (2004) identified the Northeast as the region with …

Arctic synoptic activity associated with sea ice variability using self-organizing maps
Relationships between synoptic activity and sea ice variability in the Arctic are studied using self-organizing maps (SOMs) to categorize observed weather patterns over the 1979-2010 period. The European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-interim, or ERAI) provides …

Characteristics of deep moist convection and rainfall in cut-off lows over South Africa
… according to the associated surface circulation patterns at 850 hPa. The seasonal distribution and duration of the systems over northern (10°E-33°E //22°-32°S) and southern (10°E-33°E //32°-35°S) regions of the study area were also analyzed. Results show COL systems shifting with season towards …

Ground-Level Ozone Across Kentucky: Modeling and a Synoptic Analysis of High Concentrations
… O3 while the Hi model is less accurate. Synoptic meteorology conditions were analyzed to find patterns that are associated with high O3 concentrations for rural areas. Data collected at Mammoth Cave National Park (MCNP) (30 miles north of Bowling Green, KY) during 1998 to 2005 was used in …

Characterisations of Different El Nino Types, their Physical Causes and Predictions
… the amplitude of Kelvin waves as they propagate. Synoptic pattern analysis suggests that most WWBs are caused by cyclones with the combination of an active Madden-Julian Oscillation. The NorESM is able to reproduce many characteristics of observed WWBs, OHC anomalies and their relation to Kelvin …

Characteristics of precipitation and extreme precipitation events over the Drakensberg Mountain range in past and future climates
… Map (SOM) technique was employed to group the synoptic patterns over southern Africa, WERE patterns over DMR, and the future climate change projections over the Drakensberg Mountains. Results of this dissertation reveal that the weak synoptic days, which are associated with highpressure systems …
