In addition, a thought of how to use the mesoscale convergence center, TBB of convective cloud and the radar echo for rainfall rate to predict the mesoscale rain cluster is presented.

提出利用逐时的中尺度辐合中心、卫星红外云图云顶亮温及雷达回波降水率做中尺度雨团量级预测思路。

The strength of SCSSM is also related to the phase of30~ 60 day oscillation of TBB arrived over SCS during the onset period of SCSSM.

它爆发的强度还与爆发期间大气对流的30～60天振荡到达南海的位相有关；

MCS number in the early afternoon was over twice that in the early morning and the number of MCSS with TBB ≤ 54 ℃ was five times as many.

午后MCS数是上午前期的2倍以上，并且云顶亮温≤-54℃的多达5倍以上；

The anomalous features of ITCZ and subtropical high are analyzed in the period of June~ August 1998 using TBB from GMS and conventional data.

At the beginning of 2011, after a mass of redemptions from clients, UBP had seen its hedge fund investments dwindle to just$ 14bn.

2011年初，在客户大量赎回之后，该行的对冲基金投资额缩水至仅140亿美元。
