Abstract: A high coverage of weather warning is the key to improve the ability of weather disaster prevention and mitigation. The special assessment shows that the coverage of weather warning has reached an all-time high: 77 percent in the fi rst half of 2012; In all mass mediums, mobile phone messages take the fi rst place, by which the coverage has accounted for 61.75 percent; Television takes the second place, by which the coverage has accounted for 15.58 percent; Internet and the rest ways have respectively reached 13.59 percent and 3 percent. With the coverage of weather warning increasing, mobile phones and network are becoming the most important mediums for communication. The introduction of the information technology to weather warning dissemination will shorten the warning-receiving time for the public, widen the range and increase the amount of information dissemination.
