This analysis investigates the seasonal dynamics of temperature and precipitation in Piracicaba, Brazil, using long-term climate data. By grouping data by season and year, we examined how average seasonal temperatures (TMED) and total seasonal precipitation (Chuva) have evolved over time and how they relate to each other.
The results reveal a clear trend of increasing average seasonal temperatures over the years, particularly in Verão (summer) and Inverno (winter). These seasons have shown a consistent upward trajectory in temperature, indicating a warming climate. Summer remains the hottest season, but even the traditionally cooler winter has experienced a noticeable rise in average temperatures. This seasonal warming trend aligns with broader patterns of regional and global climate change.
When analyzing the relationship between temperature and precipitation, we found a weak to moderate negative correlation between seasonal average temperatures and total precipitation. In other words, seasons with higher temperatures tend to receive less rainfall. This pattern is especially pronounced in summer and spring (Primavera), suggesting that hotter seasons are also becoming drier.
These findings have important implications for agriculture, water resource management, and ecological planning. Increasing temperatures combined with reduced seasonal rainfall could exacerbate drought risk and impact crop productivity. Continued monitoring of these trends is essential to inform adaptive strategies in the face of ongoing climate change.
Two visualizations were created to support this analysis:
- A line plot showing seasonal average temperatures over time.
- A scatter plot depicting the correlation between temperature and precipitation by season, with a regression line to highlight the trend.
Together, these insights provide a clearer understanding of how seasonal climate conditions are shifting in Piracicaba and offer a foundation for further climate impact studies.
