        有關(guān)天氣變化的俗語(yǔ)

        字號(hào):

        在今天,氣象的“臉”已經(jīng)變得越來(lái)越科學(xué)了,可是老人們?nèi)越蚪驑?lè)道于一些有關(guān)天氣氣象的通俗的民間智慧,中國(guó)人如此,西方人也如此。
            Did you know?
            ◎Sound travels farther before a storm
            ◎Ropes tighten before a rain.
            ◎Rainbows are always opposite the sun.
            ◎City temperatures are almost always 5 - 10 degrees warmer than the surrounding suburbs.
            ◎Clouds cover two-thirds of the earth.
            ◎Raindrops fall at speeds between 7 and 18 miles per hour.
            For centuries, sailor and farmers relied on folklore(民間智慧) to predict(預(yù)測(cè)) the weather. As modern forecasting techniques became more accurate, most of these old tales were dismissed(不用了). But some have valid(有效的) scientific explanations.
            Mackerel sky, not three days dry.
            天色泛魚(yú)鱗,必?zé)o三日晴
            Mackerel sky refers to clouds that look like fish scales(魚(yú)鱗). These cirrocumulus clouds(卷積云) are high, rippled(起漣漪的) ice crystals(結(jié)晶) that show up in advance of a storm system and may predict rain.
            When dew is on the grass,rain will never come to pass.
            草上露珠閃,告別下雨天
            The formation of dew(露珠) requires nighttime cooling(降溫). This usually occurs best on cloudless, still(無(wú)風(fēng)的) nights, so the chance of rain is unlikely.
            Red sky at night, sailor's delight.Red sky in the morning, sailor's warning.
            晚上天色紅,水手樂(lè)呵呵;早晨天色紅,水手急煞煞。
            A red sky is the result of light passing through contaminants(污染物) held close to the earth by high air pressure(氣壓). These particles scatter away some of the shorter wavelengths(波長(zhǎng)) of light (violets and blues), leaving only the longer wavelengths (the oranges and reds). A red sky is a reliable indicator (可靠的預(yù)示) of a high-pressure(高氣壓) system, which generally brings fair weather.
            A red sky in the morning is the result of sunlight reflecting through clouds moving in from the west, which could bring bad weather.
            Fish bite best before a rain.
            大魚(yú)吃小魚(yú),天空要下魚(yú)
            The drop in barometric pressure(氣壓) before a storm sets into motion a chain of events(引起連鎖反應(yīng)): Bubbles formed by decaying products(腐爛物) on the lake bottom start to expand, making some of the matter buoyant(有浮力的) enough to rise. As minnows (淡水小魚(yú)) start to feed on the rising matter, larger fish begin feeding on the minnows.
            When a halo rings around the moon or sun, rain is approaching on the run.
            太陽(yáng)月亮鑲銀邊,老天馬上要下雨
            The halo(光圈) is caused by refraction (折光) of light through cirrostratus clouds (卷層云). These clouds are similar to cirrocumulus, but they appear smooth instead of rippled. They indicate a possibility of an approaching storm system.
            Mountains in the morning. Fountains in the evening.
            早晨天上積雨云,
            晚上地下降暴雨
            Mountains refer to massive(大片的), cumulon-imbus(積雨云) morning clouds that indicate possible late-afternoon thunder-storms.
