Foreword: "If it's hot or not, just look at June 22", June 22 today, and it's so hot that you cry this summer?
In China's long-standing folk culture, there are many proverbs about solar terms and weather changes, which are not only the crystallization of the wisdom of working people, but also an important embodiment of the ancients' observation of nature and summarizing the laws. "If the dog days are not hot, it depends on June 22", this saying is a prediction of the high temperature in summer, especially the heat of dog days, and today, it is the 22nd day of June in the lunar calendar, a special day that may reveal the temperature trend of dog days this summer.
### A modern interpretation of ancient wisdom
First, we need to understand the background and scientific basis of this proverb. In the lunar calendar, June is often the middle of summer, when the direct sun shifts northward and the solar radiation energy received by the northern hemisphere reaches its peak, so the temperature is generally high. As a time node, "June 22" may be based on long-term meteorological observation and experience accumulation, and is believed by the ancients to have some relationship with the degree of heat of the dog days that followed. Although modern meteorology does not directly confirm the direct influence of this specific date, it reflects the keen perception and naïve prediction of weather changes by the ancients.
### Origin and characteristics of dog days
Dog days, the hottest period of summer, are divided into the first, middle and last days, usually occurring from mid-July to late August in the Gregorian calendar. During this period, due to the highest accumulation of heat on the surface and the control of weather systems such as the subtropical high, most parts of the continent are in a high temperature and humidity environment, which is often called "sauna day". The heat of dog days is not only because of the high temperature, but also because of its unbearable heat and humidity, which makes the human body feel extremely uncomfortable.
### Meteorological observations on June 22
Returning to today's June 22, we may be able to try to interpret the possible direction of this summer's dog days from the current weather conditions, atmospheric circulation, ocean temperatures and other factors. For example, if the northern region is frequently affected by the convergence of warm and humid airflows and cold air in the near future, and there are frequent rainfall processes, then this may alleviate the heat of the upcoming dog days to some extent; On the contrary, if the subtropical high takes control of the central and eastern parts of the continent in advance and steadily, bringing continuous sunny and hot weather, then this year's dog days will undoubtedly be even more difficult.
### Impacts of climate change
It is worth noting that in the context of global warming, extreme weather events are frequent, and summer high temperatures are also showing an increasing trend. In recent years, many places have frequently set high temperature records, and dog days have become a critical period to test the city's ability to cope with extreme weather. Therefore, regardless of the weather on June 22, we should be prepared to cope with extreme heat, including stepping up heatstroke prevention and cooling measures, arranging outdoor work time reasonably, and raising public awareness of heatstroke prevention.
### Modern Revelations of Traditional Culture
This proverb is not only a simple prediction of weather changes, but also contains the wisdom of the ancients to conform to nature and live in harmony with heaven and earth. In modern society, although we have more advanced weather forecasting technology and climate models, these experience summaries of the ancients still have a certain reference value, reminding us to always pay attention to natural changes, respect the laws of nature, and respond to extreme weather events with scientific methods to ensure the sustainable development of human society.
### Conclusion
Today, June 22, whether or not it is an accurate predictor of the heat of this summer's dog days, we should take this as an opportunity to increase our awareness and resilience to climate change. Let us enjoy the convenience brought by modern technology, but also do not forget to inherit and carry forward the precious wisdom left by the ancients, and jointly protect this only home on earth. As for whether this summer's dog days will be "hot enough to cry", perhaps only time will give the final answer, and what we can do is to be fully prepared to respond to all changes.
