I'm not the one that came up with the idea that the US has worse weather. I got the idea from that article.
>The volatile weather in the eastern United States differs from the more moderate climates of western Europe because it is largely controlled by eastward-flowing air masses that approach over land instead of air masses that arrive from over the ocean and cause temperatures to shift more gradually.
Europe doesn't have hurricanes. Europe has 1/4 as many tornadoes as the US.
Which part of Iberia's weather are you referring to?
Any Texans wanting to talk about their special case can have a look at Iberia and its meteorology, for example.
The notion that North American weather is anomalistic is false.
