Measuring Spring Frost Intensity: A Key to Understanding Crop Yield Impacts

It is crucial to recognize that spring frost's impact on crops is a multifaceted issue affected by various factors, including temperature fluctuations and the duration of frost events. These factors can be used to gauge the intensity of spring frost occurrences. Previous research has defined frost intensity by the number of days with frost during a specific growth stage. While this method helps estimate the impact on crop yield, it overlooks crucial aspects such as temperature differences, fluctuations, and the duration of continuous frost events.

These overlooked factors not only reflect how global warming influences frost intensity but also aid in assessing its global impact on crop yield. While these factors may collectively impact yield, the mechanism of their effect remains poorly understood. Therefore, establishing a standardized method for measuring spring frost intensity is essential to investigate the link between yield reduction and the severity of frost events.
