Understanding Weather

A comprehensive, institution-grade exploration of weather and atmospheric behavior — designed to build deep intuition, structured vocabulary, and system-level understanding.

Flagship Curriculum Living Program Coming Soon: Lessons + Diagrams

This page is the master index and program map. It will continue expanding with lesson pages, diagrams, checklists, guided labs, and reference material.

Welcome & How This Works

This curriculum is built to teach weather as a system. Every chapter is designed to be: clear, visual, structured, and usable in the real world. You can study linearly or follow a track.

Beginner Friendly

Start from scratch with clear language, strong examples, and progressive depth.

Institutional Structure

Organized like a formal program: foundations → methods → systems → synthesis.

Built to Grow

New lessons, diagrams, labs, and references will be continuously added.

Learning Paths

Beginner Track

  • Foundations → Building Blocks → Moisture → Clouds → Wind → Systems
  • Goal: build “why” intuition and basic weather literacy
  • Coming Soon: guided weekly plan + practice prompts

Intermediate Track

  • Energy balance → stability → vertical motion → precipitation → systems
  • Goal: understand processes well enough to explain outcomes
  • Coming Soon: mini problem sets and guided data interpretation

Advanced Track

  • Scale interaction → persistent patterns → uncertainty → case studies
  • Goal: integrate signals, build structured reasoning, develop pattern thinking
  • Coming Soon: annotated events + structured analysis templates

Foundations of Weather

Weather emerges from imbalance: energy differences across space and time create motion, moisture transport, and evolving systems.

  • What weather represents: state variables and change
  • Why weather is dynamic: gradients, mixing, adjustment
  • Why “pattern recognition” matters more than memorizing terms
  • Coming Soon: “How to look at the sky” observation primer

Atmospheric Building Blocks

These are the fundamental pieces that explain most weather outcomes. Every advanced topic relies on these basics.

Temperature

Heat content, gradients, and their role in motion.

Pressure

Weight of air, gradients, and why winds form.

Density

Why air rises, sinks, and stratifies.

Moisture

Water vapor, saturation, and phase change energy.

Forces

What accelerates air and what resists motion.

Time

Rates, persistence, and why timing matters.

Coming soon: each card above becomes a dedicated “core concept” lesson with diagrams and quick checks.

Glossary & Dictionary

This glossary is intentionally designed to support the curriculum structure. It will expand continuously. Each term is defined in plain language first, followed by deeper context.

Core Terms (Start Here)

Atmosphere
The layer of air around Earth where weather happens.
A compressible fluid governed by energy balance, pressure, and motion; it forms layered structures and exchanges moisture and heat continuously.
Pressure Gradient
A difference in air pressure across distance.
A primary driver of wind; air accelerates from higher to lower pressure, modified by friction and rotation.
Dew Point
The temperature where air becomes saturated and moisture condenses.
A direct indicator of moisture content; higher dew points imply greater water vapor availability for clouds and precipitation.

Coming soon: expanded glossary categories with 150+ terms organized by the curriculum sections above.
