Climate for Station: Teniente Alejandro Velasco as, Cusco, Peru

The climate profile of Teniente Alejandro Velasco Astete Airport reveals a complex interplay of warming and cooling trends, with a notable decrease in precipitation concentration. While the all-time data indicates a warming trend, recent years show a cooling in high temperatures, suggesting dynamic climatic shifts in the region influenced by its unique geography.

Andean Climatic Influence

Located at -13.536, -71.939, Teniente Alejandro Velasco Astete Airport is nestled in the Andes, which exerts a significant influence on its climate. The region's Köppen classification is typically Cwb, denoting a temperate highland climate with dry winters. The surrounding mountains act as both a barrier and a moderator, influencing temperature and precipitation patterns. The altitude and terrain contribute to the marked diurnal temperature variation, with the all-time record high reaching 29.9°C (85.8°F) and the record low plunging to -7.0°C (19.4°F).

Temperature Trends: A Tale of Two Intervals

The all-time temperature trends at this station reveal a warming pattern, with high temperatures increasing by 0.53°C (0.95°F) and low temperatures by 0.50°C (0.90°F). However, the past decade presents a contrasting narrative. High temperatures have experienced a cooling trend, decreasing by 0.57°C (1.03°F), while low temperatures continue to rise by 0.45°C (0.81°F). This dichotomy highlights the complexity of local climate dynamics, possibly influenced by regional atmospheric changes and global climate patterns.

Precipitation Patterns: A More Even Distribution

The Precipitation Concentration Index (PCI) has decreased from a baseline of 18.5 to a current value of 15.3. This suggests a more even distribution of rainfall throughout the year, as a lower PCI indicates less concentration of precipitation in fewer events. Such a change can have significant implications for local agriculture and water management, aligning with Peru's regional climate goals to enhance resilience against climate variability.

Regional Thermal Oscillations

The thermal oscillations observed at Teniente Alejandro Velasco Astete Airport are indicative of broader climatic shifts. The cooling trend in high temperatures over the last decade contrasts with the long-term warming trend, suggesting potential variability in atmospheric circulation patterns or localised environmental changes. These oscillations underscore the importance of continuous monitoring to understand the implications for local ecosystems and human activities.

Implications for Climate Adaptation

As Peru continues to address its climate goals, understanding the nuanced climate dynamics at stations like Teniente Alejandro Velasco Astete is crucial. The observed trends and changes in precipitation distribution provide valuable insights for developing strategies to mitigate climate impacts, particularly in regions reliant on agriculture and water resources.
