As we all know, the ocean covers more than 70% of the Earth's surface area, is the source of major global climate and weather drivers, and is at the heart of global development goals such as sustainable development, climate change and disaster risk reduction. The ocean breeds different kinds of weather and climate phenomena, such as El Nino event, La Nina event, typhoon and tropical cyclone activity, and gives birth to extreme weather and climate events with strong destructive power and wide impact on the earth. It is the movement of ocean currents inside the ocean and the circulation between the land and sea that has shaped the colorful natural landscape and the complex and diverse weather and climate phenomena on Earth.

A growing number of observations show that the Earth's climate system is now in a very fragile equilibrium. Today, the interaction between ocean and atmosphere has become the focus of attention as the impact of climate change becomes more and more prominent. It is more important than ever to observe the oceans more closely and to understand their effects on climate and changes in ocean currents.

The 21st century is the maritime century, and Marine meteorological services have become an important guarantee for building China into a meteorological and maritime power. The 14th Five-Year Plan period is the first five-year period to build on the momentum to comprehensively promote the construction of China's meteorological power, and vigorously develop Marine meteorological undertakings, which is also an important goal of the national level during the period.

Wuxi Jiufang Technology Co., Ltd. is a high-tech enterprise, which is rooted in the national supercomputing Center in Wuxi and held by Tsinghua University, focusing on atmospheric and Marine forecasting and commercial meteorological services. It is the leading company in China that integrates supercomputing, numerical simulation and artificial intelligence. It is a technology provider of meteorological solutions for commercial meteorology, intelligent environmental protection, transportation and shipping, disaster prevention and reduction, smart city, finance and insurance and other industries.

At present, based on the intelligent weather forecast platform developed by Nine Party, it has developed and launched a number of forecast products, covering many fields such as air quality, ocean, port, meteorological navigation, ENSO, typhoon, storm surge, and involving many industries such as intelligent meteorology, atmospheric environmental protection, ocean shipping, intelligent energy, finance and insurance, disaster prevention and reduction, and smart city.

Among them, in the field of Marine meteorological services, Jiufang Technology has been making continuous efforts in smart meteorology, ocean shipping, disaster prevention and reduction, Marine environment and other aspects:

Intelligent weather

Based on high-precision atmospheric and Marine meteorological data, the intelligent grid forecast system developed by Jiufang Technology can accurately predict the global meteorological conditions in the next 7 days. It can view and analyze the global weather reality, environmental forecast, change trend and early warning data in real time to help users quickly obtain valuable meteorological and environmental information.

Based on the intelligent grid forecast system, a refined atmosphere and ocean forecast field with a resolution of 800 meters can be established in the designated sea area to provide weather forecasts of wind, wave, current, sea temperature, sea salt, sea surface height and many other elements. It provides data support and technical service support for port meteorological support service, ship dispatching and operation, offshore wind power and energy exploitation, seafood aquaculture, watershed water level forecast and early warning and other businesses.

At present, the forecast system has been successfully applied to Tianjin Port, Ningbo Port, Guangdong-Hong Kong-Macao Greater Bay Area, etc.

Ocean shipping

The ocean-going shipping meteorological navigation system developed by Jiufang Technology deeply integrates atmospheric forecast, ocean forecast, ship hydrodynamic analysis, optimization algorithm, etc., to provide refined Marine meteorological navigation services for ocean-going merchant ships, cruise ships, cargo ships, scientific research ships, and provide various kinds of path planning, such as the shortest path, the shortest time and the most economical fuel consumption.

The ocean-going meteorological navigation system can meet the different needs of various roles in shipping, such as shipowners, captains and charters, and can be applied to different scenarios such as onshore monitoring and guidance, offshore driving, voyage evaluation, etc. In the future, it will be used for scientific research in the South and the Arctic and support for special missions.

Disaster prevention and mitigation

The integrated typhoon-storm surge forecasting system developed by Jiufang Technology is the first of its kind in China with a high resolution (1km) of sub-city level and sub-street level, which integrates typhoon and storm surge. It can effectively forecast the typhoon path, intensity and the process of water increase in coastal areas under the influence of typhoon.

This system provides 120h three-dimensional precise forecast of typhoon, and 48 hours ahead of the warning information of typhoon, floodplain and embankment, so as to assist smart city planning, sponge city construction, government emergency decision-making, etc., and provide scientific and technological guarantee for the safety and development of coastal cities.

Marine environment

The Marine biochemical environment early warning and prediction system developed by Jiufang Technology is the first simulation and simulation platform of coastal Marine environment evolution in China. It provides the coupled refined simulation of waves, tides, currents and biochemistry in offshore areas of China, and can quantitatively assess the impact of coastal pollution discharge on Marine ecological environment, and realize the refined forecast of Marine nutrients, salts and phytoplankton. It serves for offshore red tide warning and forecast, and provides guarantee services for Marine environmental protection and seafood aquaculture.

Join hands to meet challenges, protect the blue planet and build a green home

 Marine national defense security and the construction of the 21st Century Maritime Silk Road provide high-quality marine meteorological service guarantee, and provide scientific support for promoting the harmonious coexistence of human and nature, achieving the goal of reaching the carbon peak and the vision of carbon neutrality.
