Radar Meteorology

← Back to Domain-Specific Abstractions by Domain

2 domain-specific abstractions whose origin domain is Radar Meteorology.

• Lemon technique — A weather-radar interpretation method that assesses relative thunderstorm updraft strength from echo-top, tilt, overhang, weak-echo-region and reflectivity-gradient trends.
• Tornado debris signature — A dual-polarization weather-radar pattern in which lofted nonmeteorological debris co-occurs with a tornadic velocity signature, providing strong evidence of an ongoing damaging tornado.
