Abstract

Urban areas have been found to affect the atmosphere locally through changes in emissions, thermal properties, the addition of moisture, and changes in airflow patterns. This study assessed the relationship between urban areas in central New Mexico and thunderstorm intensity and duration between 2001 and 2020. Weather radar data was used to derive thunderstorm events, as it is well-suited to fast-changing thunderstorm conditions. Regression analyses were used to determine the relationship between developed land cover and thunderstorm intensity and duration, while controlling for factors such as elevation, aspect, and near-surface temperatures. It was found that developed land cover was statistically significant and positively correlated with thunderstorm intensity and duration. Additionally, although developed land cover and the population of central New Mexico increased, it was found that maximum intensity, mean intensity, and duration did not increase between 2001 and 2020. Maximum intensity in the 95th percentile did increase during that time.
