Rex blocks edit

The reference to 'Rex blocks' as consisting 'of a high situated to the north of a low' needs to be debated a little. According to the US National Weather Services site it is indeed: Rex Block - A blocking pattern where there is an upper level high located directly north of a closed low. However all blocking patterns occur when the high is poleward of the low and hence to the south in the southern hemisphere. If a 'Rex block' is specific to the USA as I have not heard of it before [I live and work in the field within Australia], then I believe that its definition should be referred to as being specifically a USA phenomenon, because no blocking pattern in the southern hemisphere arises with the high to the north of the low.

The current content makes no specific mention of this being the case and should be altered accordingly.

Re: Nsdave's comment from 2008: Article now refers to "Northern Hemisphere" etc. edit

I live in the Northern Hemisphere. Nsdave's comment in 2008 would have been about the article as it was then. I had never heard about Block (meteorology) until very recently, when the article was linked from 2021 Western North America heat wave. I suppose Nsdave's comment is no longer needed. I'm not bold enough to delete Nsdave's comment here. Oaklandguy (talk) 20:48, 8 July 2021 (UTC)Reply
