The special stamp set Meteorological Achievements was issued on November 22, 2000. It consists of four stamps with a total face value of 5.20 yuan. It was designed by Zhang Lei and printed by Henan Post and Telecommunications Printing Factory using offset printing. The year 2000 marked the 50th anniversary of the establishment of the World Meteorological Organization. China Post issued this stamp set, selecting four representative meteorological science and technology achievements to showcase China's development level in modern meteorological observation, scientific research, forecasting, and weather modification.

Meteorological services are related to disaster prevention and mitigation, industrial and agricultural production, and national life. The stamp set follows the operational chain of meteorological observation, field research, forecasting technology, and artificial regulation, selecting four directions: meteorological satellites, Tibetan Plateau meteorological expeditions, numerical forecasting, and artificial rain enhancement. From space monitoring, plateau scientific expeditions, computer forecasting, to weather modification, it comprehensively showcases China's meteorological modernization achievements and reflects the value of meteorological science and technology in serving society and protecting people's livelihoods.

Stamp Designs and Historical Background

Meteorological Satellite

The main image is the Fengyun-2 geostationary meteorological satellite paired with a ground receiving antenna. Fengyun-2 is China's first-generation geostationary meteorological satellite. It continuously monitors atmospheric information such as cloud systems, typhoons, and water vapor from space, with a wide observation range and fast timeliness. It is the core equipment of China's meteorological remote sensing monitoring system, providing key space observation data for weather forecasting and disaster early warning.

Tibetan Plateau Meteorological Expedition

The stamp shows meteorological researchers conducting field meteorological observation operations on the Tibetan Plateau. The Tibetan Plateau has a major impact on the East Asian atmospheric circulation and global climate. China has long carried out comprehensive plateau meteorological scientific experiments, setting up observation equipment, collecting plateau meteorological data, promoting the development of plateau meteorology, and deepening the understanding of Asian climate patterns.

Numerical Forecasting

The stamp presents computer equipment, meteorological data, and meteorological cloud images. Numerical weather forecasting relies on atmospheric dynamic equations and uses high-performance computers to simulate atmospheric evolution. It is the core technology of modern weather forecasting, greatly improving forecast accuracy and marking China's weather forecasting entering a digital and scientific era.

Artificial Rain Enhancement

The stamp depicts meteorological aircraft conducting artificial rain enhancement operations in the air. According to cloud conditions, catalysts are seeded to promote the condensation of water vapor in clouds to form precipitation, used to alleviate drought and conserve water sources. It belongs to weather modification technology and is an important meteorological means for disaster prevention and mitigation and ecological water replenishment in China.

Artistic and Design Features

The stamp set uses modern scientific and technological realistic painting. The images are simple and clean, highlighting equipment and operational scenes, with steady and restrained colors. The offset printing provides soft layers, clearly presenting details of satellites, computers, aircraft, and other equipment. The four stamps cover four major sectors: space-based observation, field research, numerical simulation, and artificial regulation, fully outlining the modern meteorological work chain. It is a stamp set in the category of scientific and technological achievements.
