El nino is the hot dry season
la nina is the cool wet season
These periods have yearly, multi-year, decade-long, and hundreds years long cycles.
It is caused by warming or cooling of the pacific waters, which pushes air currents up along cali to washington and across the USA.
There can be some interesting weather when you are in a short term la nina/el nino and a long term one (ie. the 1-1/2 yearly cycle versus the ~7-12 year cycle).
When you have el nini cali will be hot, dry, and burn. When it flips you get all the rains.
If you learn the el nino/la nina cycles you can predict the weather of the west with amazing accuracy, and even predict the weather in the east as it also affects things here, to the point people will think you are a wizard.
You will never be tricked or confused by lying news media and moron claims of "global warming" (the earth has been COOLING the last 10+years)
