Understanding the Weather
Group Leader: Nick Ricketts
Meets: 2nd Mon from 11.00 at Palace Gate, South Street
A variety of topics ranging from local events to climate change.
Tropical storms and tornadoes are among the most destructive meteorological events on earth. Although sometimes confused, they are very different in origin and nature. Tropical storms invariably develop over warm water, since they rely on heat and moisture and often persist for several days, or even weeks. Tornadoes usually develop over land and can last from anything between a few minutes and several hours. As their name implies, tropical storms are restricted to tropical regions, whereas tornadoes have been seen on every continent except Antarctica. Nonetheless, there are favoured regions such as parts of the United States and Bangladesh.
Arctic sea ice is continuing to melt, though the rate of decline has slowed recently. Tropical Pacific sea temperatures have continued to rise and ENSO (El Niño Southern Oscillation) -neutral conditions are now present, with a 65% possibility of El Niño developing by Northern Hemisphere winter.
