Default June pressure record?


"Norman Lynagh" On the assumption that weather on one part of the planet
may have some
sort of connection, however loose, with weather on any other part of the
planet, it is interesting to see that at the time we are experiencing
near-record high pressure for June, Australia is experiencing record high
temperatures for June. A stationary high in the Tasman Sea for the past 4
days has brought N'ly winds to South Australia, New South Wales and
Victoria. This has resulted in record high June temperatures over a huge
area of these three states. Many of the records being broken have stood
for 60-80 years. More details at

I am not suggesting at all that one is a direct result of the other but
the world's weather is one single system and here are two notable events,
both substantial in size, occurring simultaneously. Fascinating.

Yes,it's interesting that the SOI (Southern Oscillation Index-roughly the
SH counterpart of the NAO ) has been highly negative this year.(and indeed
since 2001)

Cf the hemispheric indices-

the presence of large blocking HP over Iceland alone suggests a highly
negative index of zonalty in the N Atlantic region,
