El Niño and La Niña weather patterns have a significant impact on California climate. This illustration shows the drought impacts.
Long-term La Niña periods have been associated with long-term droughts in the southwest lasting 200, 90 and 55 years. More specifically severe droughts from AD1021 to 1051, AD1130 to 1180, AD1240 to 1265, AD1360 to 1365.
I often wondered what was the controlling mechanism that generated long-term La Niña conditions with few La Niño conditions. Plate Climatology Theory may be one possible answer, the generation of La Niña events by undersea volcanic activity.
I found this article on Plate Climatology most interesting.
Geologically induced “Eruptive” warm burst that helps generate 2014-2015 El Nino.
All El Ninos originate at the same fixed “Point Source” located east of Papua New Guinea and the Solomon Islands. Fixed point sources are typical of geological features, and not typical of ever moving atmospheric or ocean current energy sources.
The Papua New Guinea / Solomon Island area is the most geologically active (volcanic eruptions and earthquakes), and complex deep-ocean regions on earth.
The shape/map pattern of El Nino sea surface temperature anomalies are unique / one of a kind. These shapes do not match every changing atmospheric or ocean current shapes/map patterns.
The El Nino sea surface temperature anomalies have “linear” and “intense” boundaries inferring that the energy source is fixed at one point, and is very powerful.
The shape/distribution pattern of super-heated and chemically charged fluid flow from fixed point source deep-ocean hydrothermal vents is a very good mini-analogy of the larger El Nino ocean warming shapes/distribution patterns.
The shape/distribution pattern of super-heated and chemically charged fluid flow from fixed point source large continental/dry land volcanic eruptions is a fair analogy of El Nino ocean warming patterns.
The amount of energy needed to generate an El Nino can be mathematically modeled using a 20-by-30-mile volcanically/earthquake-active deep-sea area (“point source”). The measured energy released from the Yellowstone Plateau, a 20-by-30-mile area, is a good mathematical analogy.
El Ninos do not occur in a predictable historical pattern, rather they occur randomly. This is indicative of a geological forces origin such as volcanic eruptions which are not predictable.
El Nino-like events do not occur elsewhere in Pacific. Why? If they are atmospheric in origin, there should at least be other mini-El Ninos elsewhere. There are none.
La Niñas originate from the same fixed point source as El Ninos. This implies both are geological in nature. La Niñas represents the cooling fluid flow phase from a geological feature.
Atmospherically based El Nino computer prediction models consistently fail, likely because they are modeling the “effects” of geologically heated oceans and not the root “cause” of the El Ninos.
Historical records indicate that the first “recorded” El Nino occurred in 1525 observed by Spanish explorers. Other studies suggest strong ancient El Ninos ended Peruvian civilizations.
The main point here is that strong El Ninos are natural, and not increasing in relationship to global warming as contended by many activist climate scientists.
Your thoughts? Does this make sense? Could sunspots have an influence on plate tectonics?
