Observation & analysis
Combine surface, upper-air, radar and satellite data into a coherent estimate of the current atmospheric state.
Subject
Purpose
Weather studied through atmospheric dynamics, moisture, fronts, convection, forecasting and the evolution of finite-time atmospheric states.
Structure
Entities → interactions → mechanisms → scales → measurement
Meteorology is the short-timescale problem of diagnosing and forecasting an evolving atmosphere where initial conditions and model error both matter.
Combine surface, upper-air, radar and satellite data into a coherent estimate of the current atmospheric state.
Track pressure systems, fronts, jets and air masses as large-scale structures organizing weather.
Study instability, clouds, precipitation and thunderstorms through thermodynamics and vertical motion.
Integrate numerical dynamics from uncertain initial conditions while representing processes below model resolution.
Use ensembles, probabilities and verification to distinguish predictable structure from irreducible spread.
These separations prevent nearby ideas from collapsing into one another before the subject is understood.
forecast ≠ deterministic certainty
climate projection ≠ weather forecast
model resolution ≠ model accuracy
Use these to test whether the model is becoming explanatory rather than merely familiar.
Which weather features are limited mainly by initial-condition uncertainty versus model error?
How do unresolved cloud processes influence larger-scale forecasts?
What makes a probabilistic forecast calibrated rather than merely cautious?
Forecast skill must be evaluated against observations and baselines; ensemble spread, bias and event rarity matter as much as a single model trajectory.
