Right, my #Clojure humidity library now computes all the values that I think it should. The code could do with a bit of tidying up, there is no data validation, I have no reliable test data for the actual-vapour-pressure function, and I can't yet do the time-shifting computations I want; but nevertheless I think this is now usable and useful.

OK, in all humility, I offer to you my humidity functions library in #Clojure. They're designed to be used to investigate weather data. I've bashed these out over the weekend; they're not at all polished, and criticism and suggestions are welcomed.

My algebra is letting me down. I have a formula for deriving absolute humidity given relative humidity and temperature, which I should be able to reverse into one for deriving relative humidity given absolute humidity and temperature, but I'm totally failing.

Hi @katzenberger, I'm still struggling with getting atmospheric #humidity functions going in #Clojure. `wet-bulb-temp` now works, but I don't have working absolute humidity or vapour pressure functions.
Can you recommend a working library in any language I could crib from?

Coriolis Effect ✍️
It explains why objects moving across a rotating world seem to curve from their straight path, even when no visible force pushes them sideways. Imagine throwing a ball straight across a spinning merry-go-round. To someone standing still outside, the ball travels in a straight line. But to someone riding the spinning platform, the ball appears to bend away from its path.
The same thing happens on Earth because our planet is constantly rotating beneath everything that moves. Air currents, ocean flows, and even long-range projectiles travel over a surface that is turning while they move. This creates the illusion of a sideways force, known as the Coriolis effect.
In the Northern Hemisphere, moving objects appear to bend to the right, while in the Southern Hemisphere they bend to the left. The effect grows stronger over larger distances and faster motions, but becomes almost unnoticeable in small, everyday movements.
Scientists use this effect to understand the spinning of hurricanes, the paths of trade winds, and the circulation of oceans. It reveals that motion is not always as simple as it seems when the ground beneath us is constantly in motion itself.

Storms are changing direction due to climate change, making predictions less certain. This is a new challenge for weather experts.

@AlaskaWx absoutely fascinating to hear the short (and profound) research talks on the livestream. Yes, I wrote Senators about the urgent need to get the weather balloons up from Nome and Bethel. #WeatherScience #Climate #ClimateCrisis

Just found out about the Weather and Climate Livestream: "Starting Wednesday at 1 p.m. ET and lasting for 100 straight hours, [US] climate and weather specialists will spend 15 minutes each talking about their work and why it is so valuable for the American people."

Today's book recommendation is "Father Benito Viñes: The 19th-Century Life and Contributions of a Cuban Hurricane Observer and Scientist" by Luis E. Ramos Guadalupe, Translated by Oswaldo Garcia (2014).
From the publisher's description:
"Before Doppler radar and broadcast weather reports, Spanish-born Benito Viñes (1837–1893) spent decades observing the skies at Belen Observatory in colonial Cuba, routinely issuing weather reports and forecasts to local newspapers. And before storm trackers and emergency alerts, Viñes made it his mission to teach the public what he was learning about the weather. He developed the first network of weather observation stations in the Caribbean, and his research laid the groundwork for the hurricane warning systems we use today. His sometimes eerily accurate hurricane forecasts helped save many lives—earning him the nickname the Hurricane Priest.”I first heard of the advanced hurricane forecasting skills at Cuban weather stations when I read a book about the Galveston hurricane of 1900. That book mentioned that the Cuban forecasts had been correct, when the U.S. forecasts had been far off track. This led me to curiousity about these Cuban weather forecasting pioneers, which led me to this little book.
Originally published in Spanish, this English translation published by the American Meteorological Society tells the story of a ground-breaking weather scientist.

Today's book recommendation is "The Secret World of Weather" by Tristan Gooley (2021).
Before we can begin to understand climate change and all its ramifications, we should have a basic grasp of how weather actually works. This book is a very nice introduction to everyday weather effects that we see and feel all around us daily.
Why does it sometimes cool down at night, but sometimes does not? What do the changing shapes of clouds tell us about upcoming weather? What difference is there between wind direction at ground level and winds up at cloud level? How do clouds actually form?
The book is written for a non-scientist, without textbook language, so it's a pleasant read for anyone with a grasp of a few basic science concepts we learned in school. There are illustrations to help clarify the author's explanations, which is also helpful.
What was most interesting was that the book awakens our attention to observe overlooked facets of the world around us. Is there a nice breeze today? Pay attention to which direction it comes from, and whether it shifts as the day goes on.
When I was in high school, a half-century ago, my favorite science class was Earth Science, where we learned about weather, (along with water, erosion, and other related topics). Over the years, while my interest remained, a lot of the specific detail has blurred and seeped away. This book was a lively and engrossing refresher.
