Large-Scale Atmospheric Tourism Resource System

The Earth’s atmosphere can serve as an important tourism resource system. The lower limit is bounded by the water and land on the Earth’s surface, and the upper limit is approximately 2,000–3,000 km high. Based on the temperature, density and other physical properties, the atmosphere can be divided into several layers, including the troposphere, stratosphere, mesosphere, the thermal layer (ionosphere) and the outer sphere. The total mass of the atmosphere is 5.14 × 10¹⁸kg. Due to the influences of solar radiation, X-rays and ultraviolet radiation, the atmospheric temperature, density, and pressure vary, and such variation causes air to rise and fall to form convection and atmospheric circulation. Meteorological features such cold and hot spells, dry and wet weather, wind, clouds, rain, snow, frost, fog, lightning and scintillation create different types of weather and climate. These features are important tourism resources based on meteorology and clean air that form the large-scale...
