Don't worry, though, I won't abandon the channel. Moreover, it's possible that even more content will appear here.

One more plus: it's unclear which resource Roskomnadzor will come for next, but I hope they won't get to email anytime soon. And then, as Khodja Nasreddin used to say – either the donkey, or the padishah...

Why a newsletter? Firstly, it's easier for me to write long texts. Secondly, when I select posts for publication, I already do most of the work needed for such a digest – all that's left is to format it.

I've been eyeing email newsletters for a long time, and now I've finally decided to try this format. The first issue is already here. Subscribe and share your feedback. [santry.substack.com/p/alphafol]

Hurricane Hunters risk their lives to collect real-time data for meteorologists that cannot be obtained from satellites: vertical profiles of atmospheric pressure, temperature, humidity, and wind speed at various altitudes. Without these measurements, what's happening inside a hurricane can only be guessed from satellite images.

Falling down this rabbit hole, I found a meteorologist's blog describing a flight through Hurricane Hugo, where the aircraft experienced as much as 5g! A 90-kilogram life raft was torn from its moorings and slammed into the ceiling, leaving a dent.

For comparison: on Soyuz, g-forces during liftoff do not exceed 3–4g, and during descent on a normal trajectory, they reach 4.5–5.5g. The Shuttle's liftoff was gentler — around 3g, while during re-entry, g-forces were 1.5–1.8g during gliding and up to 2g during landing. For spacecraft, these forces are prolonged, uniform, unidirectional, & predictable. In a hurricane, it's the opposite.

During Melissa, the crew encountered turbulence of 3.8g — an acceleration 3.8 times greater than Earth's gravity. This exceeded the design limit of 3.0g, and the aircraft had to turn back.

The 53rd Weather Reconnaissance Squadron flies modified WC-130J Hercules turboprop military transport aircraft. Their airframes are reinforced to withstand the strongest turbulence at the eyewall boundary. Wind creates extreme vertical accelerations: updrafts and downdrafts literally toss the plane.

The data is transmitted to the American hurricane research center in Miami, increasing the accuracy of hurricane trajectory and intensity forecasts by 20–30 percent. Flights last ~11 hours, with enough fuel for four passes through the storm's center. The crew spends 10–20 minutes in the eye.

They use sophisticated radars to obtain the three-dimensional structure of a cyclone, but GPS drop-sondes remain the primary tool. These cardboard tubes, resembling a can of Pringles, are dropped by parachute and transmit pressure, temperature, humidity, and wind speed via radio to the ocean surface.

It is all the more surprising that since 1974, not a single plane crash has occurred during hurricane hunting. An incredible safety record despite the extreme conditions!

Falling down this rabbit hole, I found a meteorologist's blog that describes in detail and with photos a flight through Hurricane Hugo [tailspinstales.blogspot.com/20], where the aircraft experienced a staggering 5g. Then a 90-kilogram life raft was torn from its fastenings [youtube.com/watch?v=-95ZIIyDWt4] and slammed into the ceiling with such force that it left a dent on a steel handrail.
