Symbols used within the charts vary by basin, by center, and by individual preference. Simple dots or circles can be used for each position. The National Hurricane Center uses a variety of symbols composed of overlapping 6's and 9's for tropical storms and hurricanes to emulate their circulation pattern, and a circle for tropical depressions.

A mesoscale convective system's overall cloud and precipitation pattern may be round or linear in shape, and include weather systems such as tropical cyclones, squall lines, lake-effect snow events, polar lows, and mesoscale convective complexes (MCCs), and generally forms near weather fronts. The type that forms during the warm season over ...
The destruction from early 21st century Atlantic Ocean hurricanes, such as Hurricanes Katrina, Wilma, and Sandy, caused a substantial upsurge in interest in the subject of climate change and hurricanes by news media and the wider public, and concerns that global climatic change may have played a significant role in those events. In 2005 and ...
A surface weather analysis is a type of weather map that depicts positions for high and low-pressure areas, as well as various types of synoptic scale systems such as frontal zones. Isotherms can be drawn on these maps, which are lines of equal temperature.
The National Hurricane Center is responsible for the region east of 140°W, while the Central Pacific Hurricane Center is responsible for storms forming west of 140°W to the International Date Line. Atlantic hurricane – a tropical cyclone that forms in the Atlantic Ocean. The National Hurricane Center is responsible for the region.
La Niña is a natural climate pattern marked by cooler-than-average seawater in the central and eastern Pacific Ocean. When the water cools at least 0.9 degree Fahrenheit below average for three ...
Fairly soon, though, after Sept. 10, several weather patterns start to interrupt the ability of tropical storms and hurricanes to form. First, air temperatures begin to decline, and cold fronts ...
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
