Climate for Station: Clearmont 5 Sw, Wyoming, United States

Clearmont 5 Sw in Sheridan County, Wyoming, is experiencing a warming trend, with notable increases in both high and low temperatures over the past decade. The precipitation pattern has become slightly more evenly distributed, suggesting a shift in local weather dynamics.

Köppen Climate Context and Local Geography

Clearmont 5 Sw is situated in a region classified under the Köppen climate system as BSk, indicating a semi-arid steppe climate. This classification is characterised by low annual precipitation and significant temperature variations between seasons. The station's location, at the intersection of US 14 and US 16 near Ucross, is influenced by its proximity to the Bighorn Mountains. These mountains can cause orographic lifting, which affects precipitation patterns and temperature fluctuations.

Temperature Trends: A Decade of Change

Over the past decade, Clearmont 5 Sw has seen a warming trend with high temperatures increasing by 0.92°C (1.66°F) and low temperatures rising by 1.55°C (2.79°F). This trend is more pronounced than the all-time recorded increases, where high temperatures have risen by only 0.07°C (0.13°F) and lows by 0.10°C (0.18°F). This suggests that recent years have experienced a more accelerated warming, potentially linked to broader regional climate changes and global warming trends.

Record Extremes: A Climate of Contrasts

The station's historical temperature records highlight the extreme variability typical of a semi-arid climate. The highest recorded temperature is 43.3°C (109.9°F), while the lowest plummeted to -44.4°C (-47.9°F). These extremes underscore the significant thermal oscillations that can occur in this region, influenced by both altitude and latitude.

Precipitation Patterns: A Slight Redistribution

The Precipitation Concentration Index (PCI) for Clearmont 5 Sw has shown a slight decrease from a baseline of 14.20 to a current value of 13.51. This indicates that precipitation has become marginally more evenly distributed over time. In practical terms, this could mean less intense but more frequent rainfall events, which may affect local agriculture and water resource management.

Regional Climate Goals and Implications

The observed warming trends and changes in precipitation distribution at Clearmont 5 Sw align with broader climate patterns seen across the United States. National climate goals focus on reducing greenhouse gas emissions and increasing resilience to climate impacts. The data from Clearmont 5 Sw provides valuable insights into how these larger trends manifest at a local level, offering critical information for policymakers and stakeholders aiming to mitigate and adapt to climate change.
