Can OleRocks or someone else (probably someone else) explain the following caption to his cartoons in the OP???
How do you calculate a fractional degree "anomaly" relative to a 30 year period of time? And why relative to anything in that period? Isn't it more important to determine the anomaly with respect to a more contemporary time period? Why not use the LIA?
They choose the parameters based on what benefits their narrative the most. They tell you that hurricane activity is the greatest it's been in 30 years, not bothering to let you know that 50 years ago the hurricane activity was more prevelent and more destructive.
The 1950s-1960s was the last maximum "amo" the hurricane activity increases and decreases with that 30 or so year cycle within the Atlantic ocean. This period had a year like 1964 that was alot like 2004...
The 1970s and 1980s were less active with a avg from 8-12 storms a season. A nino year would have 4-6 storms like 1983, 1986, ect. Nina years like 1985, 1988, 1989 had 10-13.
That is a negative amo or cold Atlantic. A warm Atlantic or what we have since 1995-2010 has a avg of 14-15 storms a season with more hurricane activity. 1995 had 19, 2005, 28 and 2008, 2003, 16 a pieces with 2010, 19 named storms.
It is like a sine wave, which during the 1870s-1890s time frame was another active period with 1887 having 19 known storms. 1886 had like a half dozen hurricane landfalls within the gulf coast, amazing fucking season! Imagine without any thing besides crappy ship reports finding a season like that=2005? 1837 is also another possible 2005 like year. I believe that 1995, 1969 happen every 30 to 40 years and 2005 every 100 or so. Not as rare as most would think.
Negative amo from 1900-1920's then mid 1920's to late 60s positive.
No increase in activity at all. Normal Atlantic natural patterns and in fact a negative amo can give us 1979, 1980, 1985, 1992.
This is exactly true. With today's radar technology and satelite observations, we can see every gust of wind on the planet as it turns in a weather system. Nothing is missed.
Before 1978, if entire squadrons of airplanes were driven from the sky by weather, we had only a good guess that something might have happened.
Given identical weather and climate, any tally of storms from the past would be lower than a tally from today simply because the methods of data gathering are so much superior.
