降水量

Because distribution of annual rainfall amount year by year,are cruelly nonuniform,soil water resources are basically important on the growth and development of plants.

土壤水是重要的生态水源和水文要素之一，黄土高原位于干旱半干旱地区，降水量的年际变化大和季节分配极不均匀，土壤水资源对植物生长发育的影响尤为重要。

What is the average rainfall in the area?

该地区的平均降水量是多少？

The annual average rainfall of 1,000 mm around.

年平均降水量为1000毫米左右。

The annual rainfall is 400 ~ 700 mm eastern and western about 900 to 1,200 mm.

年降水量东部400~700毫米，西部约900~1，200毫米。

Temperature is also a main factor affecting the summer runoff, and the relative influences of mean minimum temperature and averaged diurnal temperature range are 34%, 31%, respectively.

春季径流量的增加归因于平均最低气温的升高，其影响程度为68%；温度同样是影响夏季径流的主要因子，平均最低气温，平均日较差相对影响程度分别为34%、31%；降水量增多、平均地温升高是秋季径流量增加的主要原因，相对影响程度分别是35%、65%；影响冬季径流的主要气候因子是冬季平均最低气温、平均地温，影响程度分别是36%，64%。

It is found that the mesoscale mountain has significant influence on the location and intensity of the heavy rain area, and the bell-mouthed area and the riverway area of Xichang are favorable to the occurrence and development of mesoscale disturbance and heavy rain.

例： 地形梯度分析表明，西昌地区所处的河谷地形和场区所处喇叭口小地形，有利于中小尺度气压扰动的发生、发展和暴雨的产生，当地形梯度减弱时，降水量相应减弱。

But the salt marsh trend to be larger.2. The reducing of wetland also has the relation with human movement.

而盐沼湿地的面积却随着降水量的减少而增加，加之年平均气温的逐步升高，盐沼湿地的面积有扩大的趋势。

Precipitation and vegetation type were the main factors affecting the sawfly diversity.

相关分析表明，降水量和植被种类是影响叶蜂多样性的主要因素。

Then, in the view of short-range weather forecast, water vapor fields in each typical process have been analyzed. The results indicate that there is significant increasing in the air column precipitable water over snow ranges when the snow is coming, snowy regions are in well agreement with the convergence regions of water vapor fluxes.

然后，利用国家气象中心T106L19全球模式的分析值格点资料等，分析各型下典型个例过程的水汽场情况，得到高原东部牧区强降雪天气前有气柱可降水量的明显增长，强降雪区与强水汽辐合区相对应，造成冬春季高原东部牧区强降雪天气的水汽主要来自孟加拉湾地区的结论。

This paper introduced a method of forecasting precipitation with frequency spectrum analysis.

本文介绍了用频谱分析法进行降水量分析和预报的基本方法。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
