typhoon season is coming. Faced with rapidly changing climatic conditions, the automatic ship identification system (AIS) is diversified. As long as the forecast information is average gusts exceed 7 levels and the waves are greater than 4 meters, it will be broadcast to ships within 30 nautical miles. It was officially launched in July. The previous typhoon Danas has been used, hoping to effectively reduce the risk of shipwrecks in the future.

The South China Sea disturbance continues to develop. The Meteorological Bureau upgraded it to tropical low pressure , and it is estimated that the 7th Typhoon of this year will be generated. In the future, the typhoon path will continue to move towards Hainan Island , which will not have a direct impact on Taiwan. However, from Thursday, under the influence of the entire large low pressure belt northward, there will be local temporary showers or thunderstorms in the eastern, southeastern and southern regions, and the range of thunderstorms in the afternoon will also expand.

Meteorological experts said that disturbances in the South China Sea increased into tropical depression at 2 pm. It is estimated that Typhoon No. 7 will be generated on Wednesday, and will move towards Hainan Island in the future and will have no direct impact on Taiwan. However, within two days, it will bring long waves to the central and southeastern areas (including Green Island, Lanyu ), the coastal areas of the Hengchun Peninsula, Penghu and Kinmen. As for the development of tropical systems on the east side of Philippines , meteorological experts say there is great uncertainty and it is estimated that there will be significant development until the weekend.

From Thursday to next Monday (August 1 to 5), the Pacific high pressure will be lifted northward, and the southern low pressure zone will also be closer to Taiwan as it lifts northward. The water vapor accompanied by the southeast wind increases, and the atmospheric environment will become unstable. There will be local temporary showers or thunderstorms in the eastern, southeast and southern regions, and other areas will be cloudy. It is worth noting that the impact of afternoon thunderstorms will also expand, and all localities must pay attention to it. In terms of temperature, the high pressure in the Pacific was strong on Wednesday, and the hot heat was felt everywhere, and the high temperature was generally above 33 degrees.

On August 23, the South Pacific instantly formed a tropical depression in an instant. The sudden 7-level gust caused 7 berths to strand seven berthed ships in the southern coast. Taking advantage of this painful experience, through the AIS shore station broadcasting sea weather warning information, it provides navigation ships with the status of walrus in Taiwan's waters at any time, so that sea ships can sail safely.

When the forecast information average gust exceeds 7 levels, waves are greater than 4 meters, and fog or typhoon occurs, the AIS shore station will be set to broadcast the pre-report warning information through the AIS shore station setting zone, and the nearest AIS shore station can be quickly sent to inform ships in dangerous sea areas to strengthen their alerts.

Taiwan’s seas wind and wave formation speed are fast, it is easily affected by the fog season in May and often faces typhoon changes from July to September. These disaster-causing factors will affect the safety of ship navigation. In the face of global climate change, effective disaster warning is very important. In the future, more application modules will be developed through AIS system to strengthen the scope of AIS’s maritime application.
