For comparison - here (quoted tweet) is last year's thread,There are lots of similarities with observable weather patterns & model forecasts as the two threads pertain to a similar state of the global energy balance.
The most notable differemce with the 2023 Equinox is that ENSO (the La Nina/El Nino oscillation) is moving into neutral which could result in a reduction of tropical convection and therefore less precipitation. However that is not yet cpc.ncep.noaa.gov/products/analy…… twitter.com/i/web/status/1…
#ClimateChangeNOW late summer update THREAD.
As winter in the north approaches we are roughly halfway to solstice/midwinter. The Sun's angle to the earth is moving south and we are seeing a burst of late cyclone activity in the Atlantic, Pacific and Indian oceans.

The ENSO oscilation remains in a strong La Nina position and seems likely to remain so for the forseeable future. Forecast models tend to predict a return to neutral ENSO but they have done so for some time now & the cause (Antarctic ice melt) may not go away.
Higher air temperatures globally increase the capacity of the atmosphere to hold water and the consequence is more #ExtrremeWeather rain events causing flooding - recently in West Pacific, Central America, South America, & Indian subcontinent. (see recent 16 day forecasts below)
Cat 1 #HurricaneJulia is now making landfall over Nicaragua, its core covers 3/4 of the Eastern Seaboard and will extreme rainfall is underway over more than 50% of the country already. The scale of the storm is comparable to #HurricaneIAN was at Cat 5 on approach to Florida.
#HurricaneJulia's IR presentation on landfall. The colour gradation represents cloud top temperature with yellow representing the coldest and highest parts of the cyclones structure.
Forecasts expect #HurricaneJulia to decay rapidly, but as it is travelling over very warm rainforested areas with lots of recent rain, and it is dragging in moisture from a very wide area of convection it may maintain more integrity than expected.

It is said that "history does not repeat" but that rather "it rhymes". And this is a #RhymingWeather reflection. Last night a massive, storm which had not been forecasted took place over Germany at night. Here is a 24 hour animation of the event.

A year and a week ago today the weather system that dumped torrential rain for 48 hours over Western Germany, and took 154 souls started.
It was this storm more than anything which woke up the Western World to the consequences of #ExtrremeWeather.

On the same day 14/July/21 the @EU_Commission issued a press release announcing the Green New Deal. And as rain was falling nearby they held a press confernce on July 15th to answer questions about the "Fit for 2055" plan which is set to transform Europe. ec.europa.eu/commission/pre…
#ExtremeWeather Split screen.
Two world's apart.
The US Eastern Seaboard and Madagascar.
The US experiencing yet another of what it calls "bomb cyclone". Madagascar about to experience a cyclone which will be much more like a bomb.

Both #Extrremeweather events caused by climate change, and 30+ years of failure to address known extreme damage to the biosphere caused by avoidable harms.
One nation responsible for the peril.
Another defenceless against it's catastrophic harms.

Another defenceless against it's catastrophic harms.
In one nation the harms will be felt mostly in travel delays.
In the other nation many will likely die, and 100s of thousands will have their lives scared and livelihoods threatened, and will likely be dependent on humanitarian aid for months if not years.

Something extraordinary is happening in the Middle East weather wise.
This thread begins in Ethiopia because it is playing a part in this, and will also receive rain from albeit not on the scale of what is happening to the north, in places where they are not used to this much.

The thread attached here is supplementary, posted earlier it contains videos mostly from @Arab_Storms who is based in the UAE whose account is documenting #ExtremeWeather events, with a focus on the #MiddleEast
It contains videos mostly from yesterday.

@Arab_Storms This thread relates to today, or more specifically the last 24 hours which has seen even greater storm activity than yesterday. This thread posted last night contains similar data to what I will be posting now about the extent and location of rainfall.
