Use the name of the connected city
Http://www.google.com/ig/api? Weather = Beijing & HL = ZH-CN (Beijing)
Http://www.google.com/ig/api? Weather = zhangka & HL = ZH-CN (Osaka)
Or
Http://www.google.com/ig/api? Weather = Beijing & HL = ZH (Beijing)
Http://www.google.com/ig/api? Weather = Osaka Ka & HL = JA (Osaka)

Which countries and cities can be found? Google also provides interfaces. The returned type can also be specified according to the output parameter.
Find country http://www.google.com/ig/countries? Output = xml & HL = ZH-CN (XML is returned)
