Introduction

This revision will adjust some observation items and increase sea ice observation projects to meet social and economic development and national early warning of disaster prevention and reduction. Requirements; increase the number of automatic observation projects and appropriately increase the specific indicators of each observation element to meet the current level of observation technology and the number of high quality According to the needs; increase the technical specifications of the new observation sensors and other equipment and installation requirements. Ship Oceanic Hydro-meteorological Auxiliary Measurement Specification

1 Scope

This standard specifies the observing items, technical requirements, and observation methods for marine hydro-meteorological aids and forecasting (hereinafter referred to as ship monitoring). Report code and data processing. This standard applies to merchant ships, fishing boats and other ships engaged in maritime activities for marine hydro-meteorological observations and data transmission.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Ship survey reports'observations The marine hydro-meteorological elements are observed and reported using the ship as a carrier. 2.2 Voluntary observing ship voluntary observingship Volunteer boat voluntaryship Obligation to undertake merchant ships, fishing boats and other ships engaged in maritime activities that obtain marine hydro-meteorological observation data and provide data transmission. 2.3 Nautical automatic metering system automaticobservationsystemofships An installation on a voluntary vessel that can automatically measure basic ocean hydro-meteorological data and other ocean waters subject to manual observation input Weather data, and instruments that are processed, displayed, stored, and transmitted. 2.4 Sea surface effective visibility sea-leveleffectivehorizontalvisibility The maximum horizontal distance within a field of vision of more than one-half the level of sea surface that a person with normal vision can see under the conditions at the time. Note. Rewrite GB/T 15920-2010, definition 4.33. 2.5 Cloud Small droplets of water or ice crystals suspended in the air or visible polymers made of a mixture of the two. 2.6 Cloudy cloudform The appearance characteristics of the cloud include the distribution of the cloud in space, its shape, its structure, and its grayscale and light transmission. 2.7 Cloud cloudmount The number of clouds covering the horizon of the sky.
