1. Typhoon Information

We are interested in using "microblog (miniblog)" for the dissemination and aggregation of typhoon information. For this purpose, we selected Twitter as an example of a microblogging service, and started an experiment using Twitter.

• Viewing Typhoon Information Follow @DigitalTyphoonE
  Following Twitter / DigitalTyphoonE (English) or Twitter / DigitalTyphoon (Japanese), you will receive typhoon information at every three hours.
• Sending Typhoon Information Follow @twiphoon
  Twiphoon is collecting information from Twitter users so please reply to twiphoon on Twitter. Replied tweets are retweeted by ReTwiphoon on Twitter.
• Querying Typhoon Information Follow @TyphoonNow
  Typhoon Now! is answering queries from Twitter users so please reply to TyphoonNow on Twitter.
• Typhoon Hashtag
  "Digital Typhoon" related sites use typhoon hashtags. For example, Typhoon 200901 has hashtags "#kujira" that represents the Asian name of the typhoon and "#TY200901" that represents the typhoon number.
• Feedback Follow @KitamotoAsanobu
  Some of the accounts above are bots, so it is a little awkward to answer your feeback. Instead, please send your feedback to @KitamotoAsanobu. Please also refer to list of twitter accounts.

For your information, we also have a Facebook version.

（Notice: September 14, 2009） Due to the specification of the hashtag, a hyphen '-' within the typhoon name breaks the hashtag. So we decided to replace a hyphen with an underbar '_' within the typhoon name.
