兴坪早霞和晚霞(夕阳)各景点摄影(绘画)路线 兴坪早霞和晚霞(夕阳)是美丽的。它随着季节的变化而变化,不断地以新面孔出现。
由于兴坪属于亚热带季风气候,每年平均降雨量1640毫米,雨水充沛,给天气变化创造了良好的条件。早晨或傍晚,太阳光斜射,通过大气层的路程比较长,光波的散射减弱很厉害。减弱最多的是太阳光波中的紫色,其次是靛、蓝色等,减弱得最少的是红色或橙色光。这些减弱后的彩色阳光,照射在天空和云层上,就形成了不同层次鲜艳夺目的彩霞。
当大气层中有微小水滴及尘埃时,加之兴坪的山体有"吸水石"的功能,光波的散射作用比单纯的空气分子更厉害。因此,当太阳在地平线上时,如果阳光所透过的远处低层大气中,有小水滴(云滴)及尘埃存在,晚霞的颜色会比没有小水滴及尘埃时更加红。这就是兴坪的夕阳特别"艳"的原故。
夏季的早晨,低空中空气稳定,很少尘埃,如果当时有鲜艳的红霞,则称为早霞。这表示东方低空含有许多水滴,有云层存在,这样的云层,在太阳还没有出来的时候,即:早晨天刚亮的时候,这就是兴坪的晨曦天气,非常壮丽,而且有气氛。随着太阳升高,热力对流逐渐向平地发展,云层也会逐渐变密,坏天气将逐渐逼近,本地天气将愈见变坏,这就是"早霞不出门"的原因。
傍晚,由于一天的阳光加热,温度较高,低空大气中的水分一般不会很多,但尘埃因对流变弱而可能大量集中到低层。因此,如果出现鲜艳的晚霞,说明晚霞主要是由尘埃等干粒子对阳光散射所致,说明西方的天气比较干燥。按照气流由西向东移动的规律,未来本地的天气不会转坏,所以有"晚霞行千里"的说法。
当然,"早霞不出门,晚霞行千里"也有例外情况。如果当太阳已落入地平线以下,地平线上的霞光应该消失了,而地平线下有大量的云层存在,地平线下的霞光也会受到云层底部的反射作用,这时,也可能会呈现出一片胭脂红色。当空气中杂质愈多时,太阳的颜色愈接近于胭脂红。这表明西方地平线下有云层存在,空气十分潮湿浑浊,预兆天气将变坏。因此又有"日没胭脂红,无雨也有风"的说法。
总之,兴坪雨水较多,天气变幻莫测。丰富多彩的艳丽景色时常可见。希望每位到兴坪来创作的朋友都能有好运气,得到丰厚的收获。 Xingping
alpenglow and afterglow(sunset) In xingping
scenery (sunset) is very beautiful. It changes with the seasons change, to have
new faces there. It is a subtropical monsoon climate,
the average annual rainfall of 1,640 mm, plenty of rain and the weather changes
to create good conditions. The morning or evening, the rays of the sun dipped
through the atmosphere relatively long distance, scattering weakened by the very
formidable. Most of the weakened sun light are purple, followed by the Indigo,
blue, weakening the least is red or orange light. These weakened after the color
sunlight, radiation and clouds in the sky, on different levels to form a colorful
cloud. The atmosphere is tiny drops of water and dust,
in addition to the Mineral Mountain "absorbent stone" function, scattering
effects than simply more powerful air molecules. Therefore, when the sun is on
the horizon, if the sunny in the distance through the lower atmosphere, a small
droplets (droplet cloud) and the presence of dust, clouds the color than the absence
of the small water droplets and dust when more red. This is particularly Xingping
sunset " bright" he added. In summer morning,
the low-altitude air stability, little dust, had a bright Fog, were called alpenglow.
This means that many of the East droplets containing low altitude, cloud cover
there, the clouds, the sun did not come out of that morning :early morning of
the time, this is the dawning of Geology weather, very magnificent, but also the
atmosphere. With the sun rising, heat convection gradually to the ground, the
clouds will gradually change, that is, to gradually approaching bad weather, local
weather grew worse, it is a " alpenglow do not go out." The
evening, as a day of sunshine heating, high temperatures, low moisture in the
atmosphere generally is not much, but because of the dust and the weak may rheological
large concentrations of low-rise. Therefore, if there is the bright afterglow
that scenery is mainly stem from the dust particle scattering of sunlight caused
show that Western relatively dry weather. According flow from west to east movement
of the law, the future of the local weather will turn bad, "afterglow running
thousand miles." In short, the weather unpredictable.Hope
every friend to be able to Xingping , the amazing nature of the accident you have
to more harvest. |
