D853 Meteorology looks at Earth's atmosphere and hydrosphere together. WGU's program guidance describes an in-depth study of the interactions that govern weather and climate, including atmospheric circulation, weather systems and climate dynamics, and the part the oceans and water cycle play in each.
The course then moves from today's weather to the changing climate, weighing natural and human (anthropogenic) causes. The challenge is rarely any single idea. It is holding several interacting causes in mind and explaining their balance without collapsing everything into one answer.

What D853 Covers
| Theme | What it means in practice |
|---|---|
| Atmospheric circulation | Why air moves in global cells and what drives winds and jet streams |
| Weather systems | Fronts, pressure systems, storms and how forecasts are built |
| Climate dynamics | Energy balance, feedbacks and long-term patterns |
| Role of the hydrosphere | Oceans, evaporation, currents and heat storage |
| Evolving climate | Natural and anthropogenic factors behind change |
Key Concepts Explained
Uneven Heating Drives Circulation
The tropics receive more solar energy than the poles. Warm air rises near the equator, spreads towards higher latitudes, cools and sinks, and Earth's rotation bends the flow. That pattern creates the large cells and prevailing winds that shape regional weather.
Example: Explain why deserts cluster near 30 degrees latitude. Air rising at the equator loses moisture as heavy rain, then descends near 30 degrees as dry air that warms as it sinks, suppressing cloud and rain. State the cause (sinking branch of the circulation cell) before the result.
Weather Versus Climate
Weather is the state of the atmosphere over hours and days; climate is the pattern over decades or longer. A cold week does not contradict a warming trend, and a strong answer says why by naming the time scale.
Feedbacks
A feedback changes the size of an initial effect. Melting ice exposes darker surface that absorbs more sunlight, which warms the region further. Naming whether a loop amplifies or dampens change is a common rubric expectation.
Example: Warmer air holds more water vapor, itself a greenhouse gas, which adds warming. Write it as a chain: initial warming, more vapor, more trapped heat, further warming, so a reinforcing loop.
Typical Assignments and How to Approach Them
WGU's guidebook does not list task prompts, so this table describes the kinds of work these themes point to. Follow your own instructions.
| Work type | What it tests | How to approach it |
|---|---|---|
| Weather analysis | Reading maps, fronts and pressure | Describe the pattern, then the likely outcome and why |
| Climate explanation | Weighing natural and human factors | Cover both, say which dominates and on what evidence |
| Data interpretation | Trends and variability | State the time scale and avoid over-reading short records |
| Teaching task | Explaining ideas to students | Choose a grade level and address one misconception |
A Study Approach That Works
- Energy first. Make sure you can explain uneven solar heating before moving on, since everything else builds on it.
- Then circulation. Sketch the global cells and mark the wet and dry zones.
- Then weather. Practice reading a fronts-and-pressure map aloud, one sentence per feature.
- Finally climate change. Build a two-column list of natural and human drivers, with evidence for each.
Where Students Get Stuck
- Single-cause answers. The course asks you to weigh natural and anthropogenic factors together. Credit goes to the interplay, not one factor.
- Mixing weather and climate. Always state the time scale.
- Listing feedbacks without direction. Say whether each one amplifies or dampens.
- Forgetting the ocean. The hydrosphere stores heat and moves it; leaving it out leaves the explanation incomplete.
Planning Table
| Stage | Goal | Evidence to keep |
|---|---|---|
| Read the task | Pull out each requirement | Rubric checklist |
| Collect evidence | Maps, data, readings | Source notes |
| Build causes | Natural and human lists | Two-column table |
| Write | Cause, mechanism, result | Draft with signposts |
| Check | Time scale and balance | Final tick-through |
Self-Check Questions
Use these questions to check that you can reason, not only recall. Answer each in two or three sentences.
- Why are the tropics wet and the subtropics dry?
- What distinguishes a warm front from a cold front in the weather you would see?
- Name one reinforcing and one dampening climate feedback and say why each acts that way.
- Which natural factors have changed climate in the past, and how do scientists separate them from human factors?
- How does the ocean store and move heat, and why does that matter for weather?
Study Tips for D853
- Explain each process aloud as if teaching a class.
- Keep one sentence per feedback loop: trigger, change, effect.
- Label time scales (hours, seasons, decades) whenever you give a trend.
- Use a map or diagram for every circulation point.
- Reserve a final read for balance between natural and human causes.

Frequently Asked Questions
WGU describes atmospheric and hydrospheric interactions, atmospheric circulation, weather systems, climate dynamics and the natural and anthropogenic factors behind climate change.
WGU's description emphasizes concepts and interpretation. Expect to read maps and data, with limited calculation. Check your course materials.
Because the course focuses on the balance of both. An answer naming only one cause usually looks incomplete.
Name the trigger, show the chain of changes and state whether the loop amplifies or reduces the original change.
No. We offer tutoring, custom answers and editing as study aids. You complete and submit your own work.
