Meteorological resources are not only fundamental but also strategic tourism resources, which are the important foundation for the integrated development of meteorology and tourism. With the intensification of global climate change, the urgent need for healthy tourism in China’s mass tourism market after the epidemic, and the rapid development of meteorological science and technology, the natural and inseparable relationship between meteorology and tourism activities and tourism economy has become more and more prominent, and “meteorology+tourism” has become a new field that is the most active and most directly perceivable by the people in the utilization of meteorological resources and innovation of meteorological services. Meteorology + Tourism” is becoming the most active and directly perceivable new field in the utilization of meteorological resources and innovation of meteorological services, and the fastest-growing and most energetic new development direction of the tourism economy in various places. Research shows that promoting “meteorology + tourism” can drive the positive coupling of the two; the deep integration and two-way empowerment of meteorology and tourism in “all-round, all-time, all-process, all-factor, all-field” is not only related to the high-quality development of tourism and meteorology but also related to the quality of tourism experience and life safety of tourists. Tourism experience quality and life safety, opportunities, and crises are surging; through seven major integration paths, “meteorology + tourism” can give rise to trillion yuan scale emerging industry clusters and should become the new focus of China’s meteorological services and tourism industry and economy synergistic and breakthroughs.

The promotion and utilization of information technology have promoted the transformation and upgrading of the industrial structure and economic structure of cultural tourism, making the traditional operation methods no longer applicable to the current operating environment. This paper analyzes the triple coupling mechanism of the cultural tourism industry, information technology and the ecological environment from the synergy of four elements: space, economy, culture and ecology. On this basis, the system dynamics concept is used to view the digital cultural tourism industry and ecological protection as a unified whole, to build a synergistic logic between the main factors in the whole, and to analyze the synergistic relationship between the two subsystems using the DPSIR framework. The results of the empirical analysis of the synergistic development efficiency of each region in China from 2011 to 2020 show that the coefficient of variation of the digital cultural tourism subsystem is the largest, which is between 1.1836 and 1.3705, indicating that the development level of digital cultural tourism varies greatly among Chinese provinces. The mean values of the integration synergy degree of the four-time nodes are 0.2226, 0.2678, 0.3549 and 0.4052, respectively, and the level of integration synergy is generally on the rise. In this paper, we effectively promote the integration of the cultural tourism industry and the ecological environment through information technology while being able to utilize ecological capital in perpetuity and realize the high-quality development of the cultural tourism industry.

A record from Wanxiang Cave, China, characterizes Asian Monsoon (AM) history over the past 1810 years. The summer monsoon correlates with solar variability, Northern Hemisphere and Chinese temperature, Alpine glacial retreat, and Chinese cultural changes. It was generally strong during Europe's Medieval Warm Period and weak during Europe's Little Ice Age, as well as during the final decades of the Tang, Yuan, and Ming Dynasties, all times that were characterized by popular unrest. It was strong during the first several decades of the Northern Song Dynasty, a period of increased rice cultivation and dramatic population increase. The sign of the correlation between the AM and temperature switches around 1960, suggesting that anthropogenic forcing superseded natural forcing as the major driver of AM changes in the late 20th century.

The wide application of microchannel arrays promotes the development of their fabrication in the direction of simplicity, low cost, and high quality. In this paper, a method of machining parallel microchannels with equal width and spacing by a cutter with multiparallel helical edge is proposed, and the response of the cutter when machining materials with different hardness (copper and nickel-based superalloy Inconel718) is explored. The tool takes only 4.5 minutes to manufacture, a significant cost saving. The time-domain signal characteristics, surface quality, burr characteristics, dimensional accuracy, and tool wear state of milling different materials are compared and analyzed. In addition, the characteristics of the chip produced by the tool are discussed. The results show that parallel microchannels with a dimensional accuracy of 118.7 ± 1.35 μm and 118.7 ± 3.61 μm can be fabricated on In718 and copper, respectively. This research is expected to be used to fabricate parallel microchannels in a variety of materials and has important application value to promote the efficient and low-cost processing of small-sized microchannel arrays.
