Jet Trails as Weather Predictors: A Phenomenon of High Altitude Humidity | January 24 2026, 02:34

Walking with Yuki, I see across the sky a very distinct and narrow streak clearly (apparently, an airplane had passed by), and usually a contrail disappears quite quickly, but today it is unusually sharp and long.

I started to investigate and it turns out this is a reliable indicator of changing weather, specifically the arrival of snow or rain: as we are actually expecting a sudden knee-deep snowfall tomorrow. In short: the airplane trail acts as an indicator of humidity at high altitudes.

Here’s how it works:

For a contrail not to evaporate but to start “smearing”, the air at an altitude of 8–10 kilometers must be very humid (saturated with moisture). If the air is dry, the ice crystals from the engine quickly turn into invisible vapor (sublimate). If the air is moist, the crystals have nowhere to evaporate. Instead, they start attracting extra moisture from the surrounding environment and grow. High humidity at high altitudes is a sure sign of an approaching warm atmospheric front.

A Decade Later: Snow, Survival Shopping, and American Winter Woes | January 23 2026, 15:56

Exactly ten years ago, on this day, my family tried to enter the USA, but it started snowing. The day after a plus 12°C

snowfall came and blocked all the roads.

And now it’s all happening again. Waiting for snow. Nadia just sent a message that there are three times more people in the grocery store than usual. Americans, when a possible zombie apocalypse approaches, stock up on food and ammunition. Ten years ago, the roads were cleared the next day, but schools, universities, and almost all offices remained closed for another week. Grocery stores opened fairly quickly (but not immediately)

To me, it’s just a typical winter

From Sunny Strolls to Snowy Storms: A Weather Whiplash | January 22 2026, 17:13

11° C warm, sunny. And tomorrow — minus 14° C, all weekend snow blizzard, from 15 to 30 cm snowdrifts.

My Ambitious 2026 Plan: From Galapagos Travel to Academic Achievements and Creative Pursuits | January 20 2026, 04:44

My plan for 2026:

– Travel to the Galápagos Islands, Ecuador for a week (summer)

– Finish and release a book on Information Retrieval (also summer, progressing slowly, first couple of chapters are already written. Already spent about 50-100 hours on this, the easy part)

– Release at least one scientific paper, probably on Data Mining (spring). Ideally, submit it somewhere to a journal (challenging). Already spent about 30 hours on this topic, a lot left to do.

– Make a step towards a PhD. Find professors, visit universities, understand the cost and assess my capabilities and resources.

– Continue studying fundamental mathematics and not die (linear algebra, calculus, probability theory, statistics, classical ML). In 2025, I spent about 200-400 hours on this topic.

– Continue studying Deep Learning and reach the “can teach” level. In 2025, I spent about 100-200 hours on this topic.

– Continue studying Data Mining/NLP.

– Update my book on RecSys, releasing version 2.0 with updates and corrections (autumn 2026)

– Make noticeable progress in painting and playing the piano. Specifically, learn Schubert’s serenade (Ständchen, D 889) completely and create at least one canvas that I wouldn’t be ashamed to give as a gift.
