Drizzle is a light precipitation consisting of liquid water drops smaller than those of rain – generally smaller than 0.5 mm (0.02 in) in diameter. Drizzle is normally produced by low stratiform clouds and stratocumulus clouds. Precipitation rates from drizzle are on the order of a millimetre (0.04 in) per day or less at the ground. Owing to the small size of drizzle drops, under many circumstances drizzle largely evaporates before reaching the surface and so may be undetected by observers on the ground. The METAR code for drizzle is DZ and for freezing drizzle is FZDZ.霧雨（きりさめ、きりあめ）または小糠雨（こぬかあめ）は、霧のような細かい雨のこと。文学など、色々なシチュエーションで使われている。気象学上では、雨滴の直径が0.5mm未満の雨と定義されている。 層雲は別名霧雲といい、雲の粒子が細かいため、雨を降らせるときは粒が細かい霧雨となることが多い。積乱雲や積雲の場合は、霧雨が降ることは少ない。 (Source: http://dbpedia.org/resource/Drizzle) |
