realization of self-adapting ikawa parameter in mm5 [PDF]

open access: yes, 2007
在"大规模科学计算在生态环境研究中的应用"项目的研究中,我们移植国际上比较成熟的软件MM5进行气象数据场的计算.在实际计算时,由于初始数据采集误差较大等原因,MM5中采用了很多固定的平滑因子,造成MM5不能模拟复杂多变环境现象,而我国地形、环境的多样性,使得数值计算结果不能令人满意.为了解决这个问题,我们引入自适应算法对软件中IKAWA参数进行自适应选择.由于是并行计算,改进引起的额外时间开销是可接受的 ...

Employment of MM5 in simulating MCSs developed in and around Bangladesh

open access: yesMAUSAM, 2009
The Mesoscale Convective Systems (MCSs) produce numerous weather hazards with their variety of forms. The formation mechanism of MCSs is thus important to know for Bangladesh and its surroundings, because this region is one of the heaviest rainfall areas in the tropical zone.
