... and we're back!
with more info on the recent happenings of la nina!
la nina threatens to wreck world weatherExperts predict a run of severe weather in the coming months, with devastating floods striking some parts of the world while severe droughts afflict other regions, as the climate phenomenon known as La Niña gathers momentum.
A chronic drought afflicting southern California and many southeastern states of America could be exacerbated, with Los Angeles heading for its driest year on record.
In contrast, western Canada and the northwestern US could turn colder and snowier. Mozambique, southeast Africa, and northern Brazil may face exceptionally heavy rains and floods, while southern Brazil and much of Argentina suffer drought.
how can WE stop el nino/ la ninathe point is.. we cant!! There is nothing we can do to stop El Nino and La Nina events from occurring. The year-to-year oscillations between normal, warm, and cold conditions in the tropical Pacific associated with the ENSO cycle involve massive redistributions of upper ocean heat.
For instance, the accumulation of excess heat in the eastern Pacific during a strong El Nino like that which occurred in 1997-98 is approximately equivalent to the output of one million medium-sized 1000 megawatt power plants operating continuously for a year. The magnitude of these natural variations clearly indicates that society cannot hope to consciously control or modify the ENSO cycle. Rather, we must learn to better predict it, and to adapt to its consequences.
The challenge for physical scientists therefore is to improve ENSO forecast models, to improve our understanding of underlying physical processes at work in the climate system, and to improve the observational data base needed to support these goals. Capitalizing on advances in the physical sciences for practical purposes is a challenge for social scientists, economists, politicians, business leaders, and the citizenry of those countries affected by ENSO variations.
The promise of the future is that continued research on ENSO and related problems will be rewarded with new scientific breakthroughs that translate into a broad range of applications for the benefit of society.
that's all.. we'll be back with more information regarding this phenomenon soooon!
