UK Weather Controls and Air Masses
Explain how location and airflow produce local UK weather differences.
How to study National 5 Geography
Start from located evidence, identify the geographical process, develop each causal link and test management against the people and environments affected.
Core concepts
Concept 1
Latitude, relief, aspect and distance from the sea influence temperature, precipitation, sunshine and exposure.
Exam cue: Name the control, then trace the process to the weather outcome.
Concept 2
The five main air masses are tropical maritime, polar maritime, returning polar maritime, tropical continental and polar continental.
Exam cue: Use air-mass source direction and surface path to infer temperature and moisture.
Concept 3
Air-mass temperature and moisture depend on source region and whether the air travelled mainly over ocean or land.
Exam cue: Distinguish an upland windward effect from a coastal moderation effect.
Risk pitfalls and guardrails
Listing weather controls without explaining them.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Assuming every northern place is colder regardless of altitude or exposure.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Confusing tropical with warm all year or maritime with dry.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Memory anchors
Local-weather controls
Latitude, relief, aspect and distance from sea.
Maritime air
Travels over ocean and is generally moist.
Continental air
Travels over land and is generally drier.
Tropical maritime
Mild or warm and moist air from the south-west.
Polar maritime
Cool, moist and often showery air from the north-west.
Continental contrast
Tropical continental is hot and dry; polar continental is cold and dry at source.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
