关于我

一直从事气象预报、服务建模实践应用。 注重气象物理场、实况场、地理信息、本体知识库、分布式气象内容管理系统建立。 对Barnes客观分析, 小波,计算神经网络、信任传播、贝叶斯推理、专家系统、网络本体语言有一定体会。 一直使用Java、Delphi、Prolog、SQL编程。

本次运行1.4分钟完成41个区域所有12个气象要素的客观分析,感觉很满意了。
第五次:num area:41 sum time:85444.0 mean :2084.0
第四次:num area:41 sum time:188732.0 mean :4603.219512195122
第三次:num area:41 sum time:106780.0 mean :2604.390243902439
第二次:num area:41 sum time:474110.0 mean :11563.658536585366
第一次:num area:41 sum time:499539.0 mean :12183.878048780487
算法改进:
  1. kdtree中仅仅包含地理位置和站号,插值时根据站号获取要素;
  2. 提高分析场为600*600
  3. 使用精确尺度计算方案
  4. 根据精确尺度,调整kdtree搜寻范围,提高计算速度。
计划:
  对模块进行优化,减轻耦合。
