Meteorology: The Atmosphere in Motion
Like Duolingo, but for Meteorology: The Atmosphere in Motion. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
89 levels across 8 sections, about 178 minutes end to end, roughly 36 days at five minutes a day. It moves through Immediate Observations, Atmospheric Thermodynamics, Fluid Dynamics and Wind, Severe Weather Mechanics, Moisture and Precipitation, Global Patterns, Forecasting and Modeling, and Specialized Meteorology. It assumes you already know the basics.

Key ideas in Meteorology: The Atmosphere in Motion
- A rapid drop in pressure indicates an approaching low-pressure system or front
- Virga indicates a deep layer of dry air between the cloud base and the ground
- Pressure tendency is measured over a standard three-hour window to filter noise
- Evaporative cooling occurs as falling rain absorbs heat to turn into vapor
- The steeper the pressure fall, the more intense the arriving wind and rain
- Virga can precede 'dry-slotting' where a storm loses its ability to produce surface rain
- Using pressure tendencies to predict storm arrival
- Identifying Virga and its effect on the local environment
- Mesoscale boundaries are small-scale zones where different air masses meet
- A sudden shift in wind direction often signals the passage of a boundary
- Temperature and humidity changes usually accompany these wind shifts
- Higher cloud bases indicate a larger 'dewpoint depression' or drier surface air
- The LCL (Lifted Condensation Level) rises as relative humidity decreases
- Low, 'fat' clouds suggest high boundary-layer moisture and higher storm potential
- Locating mesoscale boundaries via wind shifts
- Estimating surface humidity based on cloud base height
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Meteorology: The Atmosphere in Motion the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
When you see rain streaks called 'Virga' that don't touch the ground, what does it tell us about the air?
