关于天气预报（谷歌，雅虎，中国气象局）的api，大家可以参考http://blog.csdn.net/fengyun1989/article/details/7341166
中国天气网(www.weather.com.cn)
通过访问http://m.weather.com.cn/data5/city.xml得到一级列表（省、直辖市、自治区）
通过访问http://m.weather.com.cn/data5/city + PROVINCE_ID +.xml得到（县级城市）列表
通过访问http://m.weather.com.cn/data5/city + CITY_ID +.xml得到城市天气预报信息ID
天气预报信息的请求地址是：http://m.weather.com.cn/data/+ WEATHER_ID +.html

1、变量名解释
temp{数字}：以date_y为基准未来六天天气情况，以摄氏度为准。
tempF{数字}：跟temp{数字}一样，只不过是以华氏度为准。
weather{数字}：天气现象。
img{数字}：天气现象的图片ID，这里可以从http://m.weather.com.cn/img/c{天气现象图片ID}.gif获取到一组图片。而每两组图片为一个图片标识分别是：白天和黑夜，因此才会有12组图片。
img_title{数字}：天气现象的图片title值。
wind{数字}：风向。
fx{数字}：风力。
最后是一些指数建议的数据。
2、数据更新频率
好像是每天的6、12、18时会更新一次，因此结合自身的情况同步更新。
整体的情况大概这样，希望整理这篇能给您带来方便。最后获取中国天气网数据是需要授权的，建议您在获取数据时先到http://www.weather.com.cn获取授权证明。
