[#ExtremeWeather #ClimateChangeNow DATA ANOMALY THREAD – Central & North America]
In this thread I release five sets of data which appear to show atmospheric geo-engineering over North America at unprecedented scale, seemingly for the purpose of keeping hurricanes away.

During observations of #Invest91L #HurricaneJulia & #TSKarl in Central America there was an issue elephant sized mystery in the room – a tangential one, namely what is going on with the Arctic?

The constant impact of a the endless series of arctic blasts on forecasts came particularly obvious when hurricanes in both the Atlantic and Pacific were shown in a forecast moving south in model forecasts.

The cause ongoing significant atmospheric temperature anomaly over the Arctic & North America, which is having a material impact on Central American weather.

The arctic temperature component of this has been noted widely (see quoted tweet). But the impact on atmospheric water movement has not.

The impact of the event in precipitable water data & satellite imagery is very obvious. A seemingly endless series of Arctic blasts of peculiarly warm air coming south over North America is keeping the continent free of moisture.

This is also preventing hurricane’s from approaching the southern United States, and significantly reducing atmospheric water over the United States as you can see.

The anomaly isalso easily observable on the ground.
1.Clear skies over Western US
2.Unseasonable warmness, especially in Alaska, the Arctic, Canada and Western US particularly – the arctic blasts are mostly moving east.

An explanation of the data - its context and implications will follow in a second thread.
For now I will describe the data collected so far: [Google Drive repository to download data >> drive.google.com/drive/folders/… ]

The data comes from publicly accessible sources:
-long range weather simulation model data from @NOAA’s GEFS Model via @weathermodels_ .
-Satellite imagery data from @Zoom_Earth and @NASA Worldview

The data shows a stationary source for the anomaly in two locations on the West and East Coast of Canada. Both locations are show a persistent atmospheric height and temperature anomaly that does not move in Zero Hour forecast data (i.e. current weather).

Primary data was collected on the 13th and 14th of October using @weathermodels_ and comes from the GEFS (ensemble model) there are five time series in the Google Drive repository. >> drive.google.com/drive/folders/…

1.Series 1: Arctic 850hpa height anomaly 10-12 October

2.Series 2: North America 850hpa Temperature Anomaly data 11-14 October

3.Series 3 : North America night time satellite imagery sequences from late Sept till today

4.Series 4. Daytime satellite imagery sequences from late Sept till today

5.Series 5. A NASA North America satellite image sequence from the same period in 2021

The overlapping temperature and atmospheric height data shows a repetitive pattern over a five day period. Satellite imagery event appears to have started earlier, but after September 26th. The data suggests it may have begun after #HurricaneIan & its remnants.

Normal weather data is natural, fluid and stochastic i.e.“having a random probability distribution.”
This weather data is not.

North America’s current weather appears to be being driven by this anomaly.

My conclusion is this cannot be natural & that therefore it is human made. I realise this is a serious claim to make, hence releasing my data for review.

I will post sufficient data here in this to make the central point clearly. The data is repetitive – which is the reason for this thread & data release.

Extreme weather that doesn’t move - that is exactly the same every day for 5 days & possibly longer - is anomalous. Very.
