Re: General July Weather
A classic strong negative Indian Ocean Dipole signature is developing in our part of the world. Warmer water off Indonesia and a cold Australian bight. Looks like the years of 2010 & 2016. I had around 300mm of rain in both of these years from August until the end of September with higher levels of equatorial moisture fueling Tasman cyclonic gyres. This set up spawned the famous South Australia tornado outbreak in late September 2016 which took out the whole state power grid. Volatile times ahead.

Re: General July Weather
We had 8.5mm of rain overnight, easing away this morning with it becoming fine and sunny from noon.
Mild day today with it getting up to 14.5C.
Cooling down this evening with a frost likely in the morning.
I see that there were a few lightning hits around the Foveaux Strait area this evening.

Re: General July Weather
Up to 88mm for the month, making it the wettest month this year. But the average for me is 136mm, so it will end up the 5th drier than average month in a row...

Re: General July Weather
I must be looking at the wrong models because both EC and GFS show absolutely nothing out of the ordinary for Brazil next week up to Friday?

Re: General July Weather
NASA > GISS currently showing it's the coolest year globally since 2014 at 0.16c above the 1991-2020 mean or 0.79c above the 1951-1980 to 30 June. So currently the coolest for 7 years but a long way to go either way for 2021's data. It would need to drop from 0.79 to 0.53 above the 1951-1980 ave in the next 6 months to be the coldest year in decades (since 2001).

Re: General July Weather
500mb streamer supported by an overhead-ish lobe of the stratospheric vortex and also a meridional polar jet merging with the subtropical version. Just the 500mb modelling from GFS here:
Imagine if we got that
Back on track with NZ weather, superb day in Kaikoura - little wind and mild temperatures. Perfect.

Re: General July Weather
i can't see the rest of the year being colder than normal
for the globe as a whole seeing the large areas of ocean above normal temperatures

Re: General July Weather
Looks like we are into the spring westerlies quite early this year. That is climate change.

Re: General July Weather
The week of westerlies coming up is not the start of the spring westerlies. It will be followed by alternating high and low pressure systems. There is very little westerly component in the six week guidance after next week/weekend.NZ Thunderstorm Soc wrote: ↑Thu 29/07/2021 18:04Looks like we are into the spring westerlies quite early this year.
