层积云

The variation in surface elements of fog has high complementariness with that of sensing images.

在卫星遥感图像上，雾与积云的纹理结构特征差别非常明显，与层云也有着一定的差别，其关系为：雾的分形维数≤层状云的分形维数＜非层状云的分形维数。

He scattered 1500 grams dry ice in cumulus layer of solid carbon dioxide, after 5 minutes, cumulus actually all became snowflake, wave in succession fall down, because air is dry, snowflake is waving fall 600 meters later, overall raising of things to a higher level is lunt.

他在积云层中撒了1500克干冰，5分钟后，积云竟然全都变成了雪片，纷纷飘落下来，由于空气干燥，雪片在飘落600米之后，又全部升华为水汽。

Most lightning occurs within cumulonimbus clouds like these, but it can also be released from wide, layered formations called stratiform clouds.

但也有的可以被比较平坦的层积云所释放。附件：您需要登录才可以下载或查看附件。没有帐号？注册

In a same cloud band, the variation of temperature is small meanwhile the temperature is lower.The convective bubbles were observed in the warm clouds under the middle of the cumulostratus on 21,June 1992. The bubbles clearly show that they are one kind of mesoscale organization. It suggests that the synoptic system is situable to produce convective bubbles. Its contrastly analysed that the particle concentration and the liquid water content are higher.the particle spectra is similar,the particles captured by 2D-C probe are bigger in the bubbles.

1991年6月21日个例观测到对流泡位于层积云下部暖云中的部分，泡状结构明显，呈现出中尺度组织特征，天气系统的配置有利于垂直上升运动的发展：通过对比分析，发现对流泡内具有云滴浓度高、液态水含量较高、云谱型相似以及2D-C粒子尺度大等特点：本次个例观测到的对流泡内云滴谱表现为单峰型。

In order to develop and modify Gregory scheme for cumulus convective parameterization,we make the improvement as follows:(1) The large-scale moisture convergence is taken into account and the organized inflow,which occurs in the area of large-scale moisture convergence and is directly proportional to it, is added to turbulent airflow.(2) The influence on saturation vapor pressure exerted by supercooled water is taken into account and the initial mass flux is adjusted. Based on diagnosis of the air heating and moistening, the downdraft airflow is adjusted.(3) Based on the character of our country heavy rainfall,which usually occurs in the mixed cloud consisted of stratocumulus and cumulus, the process of excessive convection is restrained by organized outflow in the top of cloud and improving downdraft current and by reducing the evaporation of rainfall and release of latent heat.

为了改进和发展Gregory积云参数化方案，(1)考虑了大尺度水汽辐合对积云对流的影响，即在混合卷入中加入有组织的卷入，让有组织的卷入存在于有大尺度水汽辐合的层次上，并且与大尺度水汽辐合直接成比例；(2)考虑了过冷水存在对饱和比湿的影响，调整了初始的质量通量，并且根据对大气加热加湿的诊断，调整了大气向下拖曳的强度；(3)根据我国降水多由层状云和嵌入其中的对流云混合产生的这一特点，对于过强对流过程进行抑制，在云顶加入有组织的卷出，同时加大向下拖曳的强度，减少蒸发以降低潜热的释放，抑制过强对流的发生。

Bruise-black clouds silhouetted a forest of giant gymnosperms while stratocumulus towered nine kilometers high in a violent sky.

长满巨大裸子植物的森林在乌青的黑云下现出黑色影像，而层积云就像万米高塔直插入狂暴天穹。

Transmissions at 0.75 and 1.65 μm can also be used to retrieve τ and re. 2. Study the impact of cloud inhomogeneity on the satellite retrieval simultaneously. Two 3D cloud fields, cumulus and stratocumulus fields are used in our study. The two cloud fields are generated with LES model and are adopted by the I3RC phase II. The BRDF at the wavelengths of 0.65 and 2.13 μm are calculated with SHDOM, and then the cloud optical thickness and effective particle radius are simultaneously retrieved using the MODIS algorithm. We studied the impact of cloud inhomogeneity on the satellite retrieval at high and medium resolutions. Some conclusions have been made, such as the BRDF abnormal phenomenon, the reverse relationship between τ and re, the clustering effect of over and under estimation in the retrieval of τ and re .

我们选用为I3RC所采用的由LES模式给出的具有明确物理属性的两个高分辨率三维云场－积云场与层积云场，利用SHDOM三维辐射传输模式来模拟卫星观测的辐射值，并采用MODIS算法进行反演，同时研究了在高分辨云场及中低分辨率云场下，云的非均匀性对反演云光学厚度及有效粒子半径的影响，并得到了云的非均匀性会造成的双向反射率异常，反演结果中光学厚度与有效粒子半径的负相关关系，高估或低估现象是成&簇&出现的等结论。

Of the three tropical precipitation clouds in winter in Hainan the water vapor content is the highest in cumulonimbus and varies most greatly during precipitation, the second highest in cumulus congestus and the lowest in stratocumulus opacus.

There are some main conclusions as follows:1、 In Inner Mongolia, Mean cloud amount, low cloud amount, middle cloud amount , liquid stratocumulus liquid stratus、 ice stratocumulus、 ice stratus、 ice nimbostratus cloud amount are getting more from west to east.
