A fluid mechanist engineer specialising in multiphase flows with a passion for science, motorsport, satellite imagery, astro / space and weather, in particular Cyclones, typhoons, hurricanes! Based in Western Australia but travel the world!
All major models are signalling a very active tropical Australia over the next week and a half. TLs in GoC, Timor sea, and Coral sea. Still a long way out but the consistancy between the models indicates it is worth watching.👁️👀 #Cyclone #Tropics
Holiday today + sore from snowboarding so I did a bit more of this. Wrote a simple TC center calculation code for IR data. Also migrated the plotting scheme over to Python based so it looks way nicer. Video shows brightness temp shaded every 5C and contoured every 10C. Plus marker = computed center.
Landcane over central Australia. Gorgeous. 😍
A lovely "landcane" over central australia right now! Quite rare, it is dumping tons of rain over normally parched deserts.
Stunning! #Landcane #Low #AusWX
Photo of a big new moon on the top-left of frame, shot at 500mm, with a red dot in the center of frame (Mercury) and the Griffith Observatory on the bottom-right corner.
Moon and Mercury setting next to the Griffith Observatory just moments ago. Found a good spot to take photos.

Just ❤️👌
Yes there are cases it is out of the way. Goes18 inclination is close enough to 0° (I.e. above equator) but earths axis is tilted by 23.5°, pulls moon and earths orbits are non zero incl
I love this demonstration of distance! GOES18 is in geostationary orbit 35,800 km from earth which is 9.3% further from the moon than the earths surface.
Hence the apparent size difference and annular nature of the eclipse from there
Demonstrates the extraordinary coincidence we see from earth! 🌏
Geostationary orbit is 35,800 km - distance earth to moon is 384,000 km so GOES 18 is 9.3% further… hence the size difference!

What did the Sun do today? It is eclipse season! The Moon partially obscures the solar disk in this image. #science #thesun #sciart #astronomy #heliophysics
last 6 hours of radar and satellite. #CycloneMitchell
Eastward upper outflow For STC #Mitchell looks restricted on the IR satellite loop which is likely hampering development with increasing shear also evident.
I think it has peaked and is unlikely to further intensify.
Winds picking back up on Barrow island with the backside of Severe Tropical #CycloneMitchell
Radar indicates some recent Southerly movement which may put Onslow in the firing line of the Eastern eyewall.
The last hour or so of Severe Tropical Cyclone #Mitchell viah Himawari-9 at high temporal resolution (2.5min). This is from the red, 640nm band imager.

Most recent MW images (05:25 AWST) show strongest convection is likely to be on backside of #Cyclone #Mitchell
Obs beginning to peak at Barrow Island for Severe Tropical #CycloneMitchell Pressure down to 980 hPa.
Admittedly this is resonably old (5:40am AWST 7th Feb) but it is the latest MW image with decent coverage, and it looks more impressive than I thought with really strong convection in the NE quad #CycloneMitchell.
It has definitely improved since then so Im looking forward to another good sat pass.
Large eye feature on the radar loop from Tropical Cyclone Mitchell, with outer bands hitting Port Hedland right now. Keep an eye on Barrow Island AWS as the centre of the system approaches. #CycloneMitchell
Most recent RGB satellite loop. Track map has a likely crossing near Onslow, a town of about 800 people but also crossing Barrow Island, where the worlds highest non tornadic wind was ever recorded.
Tropical Cyclone Mitchell (#21U / 20S) is a pretty large system and is currently at 982hPa Cat 2 (Aus scale) with sustained winds around the 50 kt (92km/h) mark.
With warm seas, low-mod shear tons of moisture and good outflow, it is expected to strengthen today to cat 3 with winds to 80 kt.
Tropical Low 21U -> Tropical cyclone. Seems likely for the Pilbra / Gascoyne regions of WA with all major models on the same page. It could be a nasty one too with some models down to 960 hPa. #21U
That flow tho.
You may have seen pictures, but have you ever seen video of a gigantic jet #TLE from space?

Ex TC Luana is drenching central WA right now
Mildura is seeing some seriously dry air! 48 °C with DP of -1.5 °C! #VicWx #AusWx
Former TC #Luana is over the #Kimberley region of #WesternAustralia. Another weak low pressure system is over the Cape York Peninsula, while monitoring tropical development near #Vanuatu next week.
Looks likethe broad eye feature is about to cross the coast.

Is the JWST image vertically flipped in orrientation? The lighting doesnt look correct?
