SANJIESAN LORE / Landscape design
Choose the wind before painting two mountain slopes
A green slope beside an arid plain can be a useful visual contrast, but it needs more than opposite colour palettes. NASA’s Oregon rain-shadow explanation connects moist airflow, a mountain barrier and drier conditions beyond it. Use the relationship as a starting assumption for an invented landscape, not a universal climate recipe.
Sketch the cause beside the painting
Before painting vegetation, put a small arrow on the study showing the assumed arrival direction of moist air. Mark the ridge and the side facing that airflow. Your invented planet does not have to use Oregon’s wind direction. If you reverse the wind in a later illustration, revisit the environmental explanation instead of keeping the original labels by habit. Keep seasonal changes and extraordinary world rules separate from this first simplified study.
Change details people would notice
Paint two small views of the same pass, one on either approach. Besides colour, choose three scene details: how a traveller stores a cloak, where a settlement collects water, and what material appears on exposed ground. These are fictional design decisions, not claims that every leeward settlement behaves alike. A shopkeeper who depends on imports can also complicate the visual pattern; not every object in the dry-side town must be locally produced.
Ask for an explanation of one mismatch
Place the two views beside the regional map. If a dense wet forest appears far beyond the dry basin, identify another water source, revise its placement or leave the cause explicitly unresolved. Do not solve every mismatch with an unmentioned magical spring. The exercise succeeds when the contrast has a legible premise and any exceptions have a deliberate role, while the painting still leaves room for local variation and discovery.
