Mnemonic

An ice storm rolls in from the east, flash-freezing everything it touches. Trees crack. Rivers halt mid-flow. The entire eastern countryside is left completely frozen—a silent, crystalline world where nothing moves.
Additional thoughts
Picture the wind blowing from the east carrying shards of ice that instantly freeze whatever they hit. East + Ice = Frozen. The directional origin (east) plus the substance (ice) locks in the kanji's meaning.
Quick recall
An ice storm from the east leaves everything frozen solid.
