Climate for Station: Santarem-Aeroporto, Para, Brazil

Santarém-Aeroporto's climate profile reveals a juxtaposition of warming and cooling trends, with a notable shift towards more evenly distributed rainfall. The region's all-time temperature trends suggest a warming of 0.12°C (0.22°F) for highs and a cooling of 0.25°C (0.45°F) for lows, while recent 10-year data indicates a slight cooling in highs and warming in lows. These dynamics are set against the backdrop of Brazil's commitment to sustainable climate policies.

Equatorial Climate Dynamics

Santarém-Aeroporto is nestled in the heart of the Amazon, characterised by its equatorial climate (Af in the Köppen classification), marked by high humidity and significant rainfall throughout the year. The Amazon River's proximity plays a crucial role in moderating temperatures and influencing humidity levels. The all-time temperature trends show a warming of 0.12°C (0.22°F) for high temperatures, suggesting a gradual rise in daytime heat over the years. Conversely, the lows have experienced a cooling trend of 0.25°C (0.45°F), indicating cooler nights, which could be attributed to changes in cloud cover or localised atmospheric conditions.

Recent Temperature Fluctuations

Examining the past decade, Santarém-Aeroporto has experienced a slight cooling trend in high temperatures, with a decrease of 0.16°C (0.29°F). In contrast, the low temperatures have shown a warming trend of 0.15°C (0.27°F). This divergence from the all-time trends could reflect short-term climatic variability or regional weather patterns. Such fluctuations are essential for understanding the broader implications of climate change on local ecosystems and human activities.

Rainfall Redistribution

The Precipitation Concentration Index (PCI) has seen a significant decrease from a baseline of 13.70 to a current value of 9.90. This change indicates that rainfall is now more evenly distributed throughout the year, reducing the likelihood of intense, concentrated rainfall events. A PCI below 10 suggests a very even distribution, which can mitigate the risks of flooding and soil erosion, benefiting agriculture and local communities.

Temperature Extremes and Records

Santarém-Aeroporto's climate extremes are defined by a record high of 39.0°C (102.2°F) and a record low of 17.0°C (62.6°F). These extremes underscore the region's capacity for significant thermal variation, despite its equatorial location. Such records are crucial for assessing the resilience of local infrastructure and ecosystems to temperature extremes.

Regional Climate Initiatives

Brazil's regional climate goals, aimed at reducing deforestation and promoting sustainable land use, provide a critical context for Santarém-Aeroporto's climate profile. The observed changes in temperature and precipitation patterns align with broader national efforts to adapt to and mitigate the impacts of climate change. Understanding these localised trends is vital for informing policy decisions and fostering resilience in the face of ongoing environmental challenges.
