Long-term observed changes of air temperature, relative humidity and vapour pressure deficit in Bolivia, 1950–2019

Abstract:

This study analyzes the long-term observed changes of mean (Tmean), maximum (Tmax) and minimum (Tmin) air temperatures, relative humidity (RH) and vapour pressure deficit (VPD) at different elevation ranges across Bolivia from 1950 to 2019. The linear trends in air temperature series present a significant increase, with no substantial seasonal or spatial differences. On an annual basis, RH exhibited a non-significant decrease (−0.08% decade⁻¹), while VPD showed a significant increase (0.01 hPa decade⁻¹) (p < 0.05). Although prior research has suggested that highland elevations experience faster warming than the global average, we have not identified a distinct correlation between elevation gradients and differential warming rates in Bolivia. Future research could investigate elevation-dependent climate trends by examining seasonal and monthly patterns of climatic variables in relation to topographical gradients in various highland regions.
