Spring Frost Impact on Crop Yields: Intensity, Timing, and Vulnerability Analysis

This study investigated the impact of spring frost on crop yields by defining the 'intensity' of spring frost events and analyzing its relationship with yield loss. The results indicate a positive correlation between the intensity factors (temperature anomaly) and yield loss for corn, soybean, and winter wheat, suggesting a strong link between frost intensity and yield reduction.

Furthermore, our analysis revealed that the timing of spring frost events significantly influences yield loss. Earlier occurrences during the flowering stage resulted in greater yield losses compared to later occurrences during the grain filling stage. This underscores the critical need for accurate forecasting and timely management practices to mitigate the impact of spring frost.

Additionally, the study highlights the varying vulnerability of crops to spring frost events based on crop type and geographical location. Winter wheat proved more vulnerable in colder regions, while soybean showed higher vulnerability in warmer regions. This information is essential for farmers and policymakers in making informed decisions regarding crop selection and management practices.

Our research provides valuable insights into the impact of spring frost on crop yields, emphasizing the need for effective management strategies to minimize its effects. Further research is essential to develop more accurate forecasting models and effective management practices to safeguard crop yields against the increasing frequency and intensity of spring frost events in the future.
