标准摘要
[中文适用范围]： 本文件定义了 TPEG 天气 (WEA) 应用程序，用于向旅行者报告天气信息。它向所有旅行者提供一般的天气相关信息，并不局限于特定的交通方式。此应用程序不向驾驶员提供特定的天气相关安全警告；这些警告作为 TPEG2-TEC 应用程序 (ISO 21219-15) 的一部分作为安全相关消息提供。WEA 应用程序提供多个时间段和多个可能关联的地理区域的天气相关预报和状态信息。注意：信息的呈现取决于接收设备的特定人机界面 (HMI)。因此，本文件未定义设备 HMI 的任何先决条件。本文件包含示例，帮助解释如何发送一些典型的天气报告（参见附件 C），以及 WEA 表代码和 WMO SYNOP 天气观测代码之间的建议转换（参见附件 D）。 [外文原描述]： This document defines the TPEG Weather (WEA) application for reporting weather information for travellers. It provides general weather-related information to all travellers and is not limited to a specific mode of transportation. This application does not provide specific weather-related safety warnings to drivers; these are provided as safety related messages as part of the TPEG2-TEC application (ISO 21219-15). The WEA application provides weather-related forecasts and status information over multiple time periods and for multiple, possibly linked, geographical areas. NOTE The presentation of the information is dependent on the specific human-machine interface (HMI) of the receiving device. Therefore, this document does not define any prerequisites for the HMI of the device. This document contains examples to help explain how some typical weather reports can be signalled (see Annex C) and suggested translations between WEA table codes and WMO SYNOP weather observation codes (see Annex D).
