☀️ 旱 = 日 sun + 干 dry: too much dry sun makes a drought
The top is 日 (sun) and the bottom is 干 (dry). A long stretch of dry sun with no rain is exactly a drought. Sound note: hàn here is a falling fourth tone.
旱 — sun 日 on top + 干 gān (phonetic, also 'dry')
A semantic-phonetic compound: 日 (sun) gives the meaning of dry, scorching weather, while 干 supplies the sound (gān → hàn) and reinforces the idea of dryness. The character has long meant 'drought' or 'dry spell,' as when the sun bakes the land and no rain falls.
