[06.06]中国晴天时钟(测试)
NOTE最近一阵忙碌，简单的弄了一个天气预测模型，我想也许对天文观测有用的。
作为测试，用6月3日的数据预测今晨8时的天气。
以下有几个是南十字星会的观测点。
MM5 Simulated forecast for Guangzhou:
Forecast time 08h June 6:
Geopotential/Height Humidity/Cover
850hPa/1450m 87%/Overcast
700hPa/3100m 72%/Overcast
500hPa/5900m 87%/Overcast
300hPa/9700m 77%/Overcast
MM5 Simulated forecast for Lutian:
Forecast time 08h June 6:
Geopotential/Height Humidity/Cover
850hPa/1450m 87%/Overcast
700hPa/3100m 87%/Overcast
500hPa/5900m 97%/Overcast
300hPa/9700m 77%/Overcast
MM5 Simulated forecast for Heshui:
Forecast time 08h June 6:
Geopotential/Height Humidity/Cover
850hPa/1450m 87%/Overcast
700hPa/3100m 67%/Scattered Clouds
500hPa/5900m 67%/Overcast
300hPa/9700m 77%/Overcast
MM5 Simulated forecast for Nanjing:
Forecast time 08h June 6:
Geopotential/Height Humidity/Cover
850hPa/1450m 17%/Clear
700hPa/3100m 0%/Clear
500hPa/5900m 97%/Overcast
300hPa/9700m 67%/Overcast
MM5 Simulated forecast for Shanghai:
Forecast time 08h June 6:
Geopotential/Height Humidity/Cover
850hPa/1450m 42%/Clear
700hPa/3100m 0%/Clear
500hPa/5900m 62%/Scattered Clouds
300hPa/9700m 57%/Scattered Clouds
MM5 Simulated forecast for Tsingdao:
Forecast time 08h June 6:
Geopotential/Height Humidity/Cover
850hPa/1450m 72%/Scattered Clouds
700hPa/3100m 47%/Clear
500hPa/5900m 82%/Overcast
300hPa/9700m 57%/Scattered Clouds NOTE：
给出的是不同位势，也就是不同高度层的水汽预测，然后通过水汽-云量公式转换成云量，有三种表达：Clear表示无云，Scattered Clouds表示有云，Overcast表示阴天。 支持！
小龙，注意一下数字化和标准化，便于将来自动生成GIF图像文件
参考：http://cleardarksky.com/txtc/SrtgaCAcsp.txt 多谢楼上提醒，我目前还在想办法求云量。
这个模型预测广州的准确率有70%左右，预测南京的准确率有40%左右。里面有几个参数也许还可以改的。 不明白。看不东！！用来干什么啊！？？预测天空？？
还不如看看卫星云图？ 是用来预测云量的
不过卫星云图没办法预测啊，还是变成数学模型来做预测可靠些。
