雨季

The water contents in 1m soil layer of eight vegetation types in Yuanmou dry and hot valley in rainy season(August 2 to September 2) were measured and analyzed.These eight vegetation types are Pinus caribaea plantation,Pinus caribaea+Dodonaea viscosa plantation,Albizzia kalkora natural regeneration forest;Dodonaea viscosa+Tephrosia candida plantation,eucalyptus plantation,grassland,waste land and expansive soil.

通过对元谋干热河谷区加勒比松人工林、加勒比松+车桑子人工混交林、山合欢天然更新林、车桑子+山毛豆人工混交林、桉树人工林、草地、荒坡、膨胀土8种植被类型林地1 m土层内不同层次雨季(8月2日~9月2日)土壤水分含量的分析研究得出：在雨季8种植被类型林地土壤的水分含量均较低，因其土壤的物理性能较差，故蓄水保水能力也较差；各植被类型林地土壤的有机质、养分含量均极低，按照土壤养分含量分级标准，各植被类型林地土壤的养分含量均在6级以下。

The results were as follow: At fine, cloudlet and cloud weather in rainy season,the mean value of CO 2 content varied in a range of 349 to 350ml/m\+3 at 2.8m above the canopy, 346 to 348ml/m\+3 at 0.8m above the canopy, 345 to 349ml/m\+3 at 16m inner the forest and 352 to 357ml/m\+3 at 5m above ground in the period from 9:00 to 18:00.The CO 2 content in rainy season was lower than that in dry season. At the same weather and space-time, CO 2 content in rainy season was higher than that of CO 2 in dry season at both day and night. According to the grads calculation, there were the CO 2 flux from atmosphere to canopy with 0.61×10 -6 and 0.71×10 -6kg/(m 2·s) during day time in dry and rainy seasons respectively.

采用梯度法及CI-301PS CO2系统，实现了海南尖峰岭热带山地雨林近冠层CO 2、微气象因子梯度观测研究，结果表明：雨季晴、晴间少云及多云天气，9：00～18：00CO 2浓度平均值分别在349～350ml/m3(冠上2.8m)、346～348ml/m3(冠上0.8m)、345～349ml/m3(林内16m)、352～357ml/m3(林内5m)，较旱季相应天气分别小14～17.5、10.1～23.7、1 6.4～35.7和18.1～36.1ml/m3；1：00～8：00，则雨季CO2浓度大于旱季；梯度浓度廓变量和实时动力计算反映出，8：00～18：00CO2通量由大气向林冠层，旱、雨季平均CO2通量分别为0.61×10-6kg/(m2·s和0.71×10-6kg/(m 2·s)，19：00通量甚微，20：00～7：00CO2通量则由林冠向大气，平均CO2通量分别为0.36×10-6kg/(m2·s)和0.32×10-6kg/(m2·s)；雨季昼夜大气流向冠层的净CO2通量是相应旱季的1.56倍。

In his mind, the monsoon is followed by broiling sunshine, and then another monsoon. The incessant repetition of the rotation of the celestial bodies is just the mercilessness and absurdity of time.

他想，雨季过后太阳酷热地照耀，之后又是雨季的再次到来，这种天体翻转的不断重复，恰是时间的无情和荒谬。

The main spatial and temporal distribution features of pentad precipitation in rainy season from 1991 to 2000 over Yunnan Province (84 stations) are analyzed by means of the principal component analysis method. The features of lowfrequency fluctuation are analyzed by the noninteger technique of power spectrum. The relation between lowfrequency fluctuation and El Nino and precipitation in rainy reason of Yunnan Province are studied.

应用主分量方法分析了云南省84站1991～2000年雨季(5～10月)逐候降水量的主要时空特征，并用非整波技术分析了所提取的第1，第2主分量频谱分布的低频振荡特点，同时分析了低频振荡现象与El Nino事件及云南雨季降水多，少之间的关系。

I think that it is no problem for them to finish the project before the rainy season.

我想他们在雨季之前完成这个项目是不成问题的我想他们在雨季之前完成这个项目是不成问题的。

In this study, sulfate radical concentration from 4 drip water points (PL1, PL2, SH, JG) in the Shihua cave have been monitored for three years, and those from the drip water point was monitored for two years. Drip discharges show three types of response to surface precipitation variations: rapid response, response with associated time-lag and stable. The results show that:(1) SO(superscript 2- subscript 4) concentration in rapid response drip water increases sharply during rain period and has a exponential relationship with drip rate;(2) in the drip water of lag response, SO(superscript 2- subscript 4) concentration has no significant incrcase during rainfall, but they show a increasing trend during a long-term monitoring;(3) SO(superscript 2- subscript 4) concentration at the stable drip site is low and has no obvious change during wet weason.

本文通过对石花洞洞穴4个滴水点（JG， SH， PL1和PL2）硫酸根浓度近3个水文年的分析测定，结果表明：响应降雨快的滴水点滴水SO(上标 2-下标 4)浓度升高幅度最明显，且滴水SO(上标 2-下标 4)浓度与滴率成指数关系；滞后响应降雨的观测点滴水SO(上标 2-下标 4)浓度雨季升高幅度不明显，但在长期观测期间有明显增加的趋势；对降雨没有响应的滴水点，其SO(上标 2-下标 4)浓度低且雨季没有明显变化。

For example, in the deserts, periods of wetter conditions contrasted with drier, interpluvial periods.

比如，在沙漠地带，湿润的雨季与干旱的间雨季形成鲜明的反差。

Except for Indigofera pulchella and trem a angustifolia that started to fall leaves in the middle of the rainy season, other 30 species started to drop their leaves from the late rainy season, and leaf dropping lasted for at least three months .

除红花柴和狭叶山黄麻从雨季中期开始脱落叶片外，其它30种植物从雨季末期开始脱落叶片，落叶期至少延续3个月以上。

The results show:① The predominant period bands represented in the lowfrequency fluctuation field are interseasonal fluctuations of 6 pentads (30 days) and 10 pentads (50 days) and the intraseasonal fluctuations of 15 to 17 pentads (75 to 85 days).② The 30day fluctuation period is an intrinsic fluctuation of the pentad precipitation in rainy season of Yunnan Province.③ When El Nino or La Nina happens, there is a 50day fluctuation period in the pentad precipitation in rainy season of Yunnan.④ While there is a 75-85 day fluctuation period in the pentad precipitation in rainy season of Yunnan, the precipitation anomaly percentage in the main flood period in Yunnan is positive; on the contrary, while there is no 75-85 day fluctuation, the precipitation anomaly percentage is negative.

结果表明：①云南地区雨季降水主要低频振荡周期为6候(30天)，10候(50天)的月际振荡和15～17候(75～85天)的季节内振荡；②云南雨季的候降水每年都存在30天振荡周期，30天振荡是云南雨季固有的振荡；③当发生El Nino或La Nina异常气候事件时，云南雨季的候降水存在50天振荡周期；④当云南雨季存在75～85天振荡时，云南主汛期(6～8月)降水距平百分率为正(除2000年为零距平)；当云南雨季不存在75～85天振荡时，云南主汛期降水距平百分率为负。

A planting pit about 40 cm on each side, containing a mix of surface soil, well-rotted manure and 100 g of treble super phosphate, should be prepared at the end of the dry season and the seedling planted out at the beginning of the rainy season.

在旱季结束时做好准备，在雨季一开始就种植。（在北美，一般5月到10月为旱季，12月到次年3月为雨季，4月和11月为旱、雨季过渡期。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
