Meteorology · Tropical Cyclones — Satellite Signature
On satellite imagery, a well-developed, intense hurricane typically shows:
- ANo clouds at all
- BA straight line of cloud
- CA clear, symmetric eye surrounded by a ring of deep convective cloud (the eyewall)✓ Correct
- DA single small cumulus
Explanation
A mature, intense tropical cyclone presents a round, clear eye encircled by a symmetric ring of cold (high) cloud tops — the eyewall — with spiral bands beyond. Forecasters estimate intensity from these patterns (the Dvorak technique). A ragged or absent eye suggests a weaker or weakening system.
