Did you know that Nasa will be studying el Nino from space this Winter?

El Niño is a fascinating phenomenon because it has such far-reaching and diverse impacts. The fact that fires in Indonesia are linked with circulation patterns that influence rainfall over the United States shows how complex and interconnected the Earth system is, said Lesley Ott, research meteorologist at NASA's Goddard Space Flight Center, Greenbelt, Maryland.

Using NASA satellite observations in tandem with supercomputer processing power for modeling systems, scientists have a comprehensive suite of tools to analyze El Niño events and their global impacts as never before. Throughout this winter, NASA will share the latest scientific insights and imagery updates related to El Niño.

For instance, scientists are learning how El Niño affects the year-to-year variability for fire seasons in the western United States, Amazon and Indonesia. El Niño may also affect the yearly variability of the ground-level pollutant ozone that severely affects human health. Researchers will be keenly focused on how the current El Niño will affect the drought in California.

We still have a lot to learn about these connections, and NASA's suite of satellites will help us understand these processes in a new and deeper way, said Ott.

Many NASA satellites observe environmental factors that are associated with El Niño evolution and its impacts, including sea surface temperature, sea surface height, surface currents, atmospheric winds and ocean color. The joint NASA/NOAA/CNES/EUMETSAT Jason-2 satellite measures sea surface height, which is especially useful in quantifying the heat stored and released by the oceans during El Niño years.

NASA satellites also help scientists the global impact of El Niño. The warmer than normal eastern Pacific Ocean has far-reaching effects worldwide. These events spur disasters like fires and floods. They change storm tracks, cloud cover and other weather patterns, and they have devastating effects on fisheries and other industries.

NASA's Earth-observing satellites help monitor those and other impacts by measuring land and ocean conditions that both influence and are affected by El Niño. For instance, NASA's Global Precipitation Measurement Mission provides worldwide precipitation measurements every three hours. NASA's Soil Moisture Active Passive mission measures soil moisture in the top layer of land. Both of these satellites are useful for monitoring drought, improving flood warnings and watching crop and fishing industries.

Yes, and they're getting pretty good at monitoring weather.
They said they get updates as often as every 3 hours on some things.

From what I've been hearing, thanks to El Nino, my area should have a mild and somewhat dry winter.
That's OK by me, but that also means other areas will get more severe weather.

We've been hanging in the 60s lately.
A bit warmer than normal already.

Maybe we'll get lucky and the mild weather will pass through both our areas this winter.

We have been cool but, tomorrow will be warmer. We been in the 50's tomorrow will be in the low 70's.
