The Timing of Spring Arrival in the West and the East: Climatology, Phenology, and Cultural Codes Introduction: Multiple Springs The concept of "spring arrival" is ambiguous and depends on the chosen criterion: calendar, astronomical, climatic, or phenological. Differences in timing between the West (European culture, North America) and the East (broadly — East Asia, particularly China, Japan, Korea) are caused by a complex of factors: geographical location, atmospheric circulation, cultural-historical traditions, and different systems of interpreting natural cycles. Calendar and Astronomical Frameworks: Commonalities and Differences Astronomical spring (equinox): This is the most objective but least connected to actual weather indicator. The vernal equinox, when day equals night, occurs on March 20-21 and is recognized as the start of spring both in Western and Eastern (especially Japanese) tradition. However, this is a reference point, not a description of nature’s state. Calendar spring: In the West (Gregorian calendar), spring is the months of March, April, May. In the East, especially in China, the influence of the lunar calendar persists, where spring is three months starting from the second new moon after the winter solstice (usually from late January-February). Therefore, the Chinese New Year (Spring Festival) is essentially a hope for an early spring, which can fall between January 21 and February 20. Example: In 2023, the Chinese New Year fell on January 22, which is still deep winter calendar-wise for most regions of China. However, the festival marks the sun’s turn toward spring, reflecting phenological expectation rather than actual conditions. Climatic Spring: The Role of Atmospheric Circulation Here the differences between West and East are most significant due to different configurations of climate-forming processes. Western Europe and Atlantic influence: Spring arrival here is smoother, wetter, and often lags behind calendar dates. The reason is the ... Read more
