Short Summary

This study analyzed interannual and intra-annual rainfall trends in Khénifra National Park, revealing a generalized annual decrease in rainfall and significant seasonal irregularities, with a notable decrease in spring rainfall.

Objective

• To examine interannual and intra-annual rainfall trends in Khénifra National Park, a pastoral mountain area in the central Middle Atlas Mountains.

Study Configuration

• Spatial Scale: Khénifra National Park, central Middle Atlas Mountains, Morocco.
• Temporal Scale: Interannual and intra-annual (specific study period duration not provided).

Methodology and Data

• Models used: Mann-Kendall statistical test, Buishand statistical test, Pettit statistical test.
• Data sources: Rainfall series (implied observational data from a station).

Main Results

• A generalized annual rainfall trend towards decrease was observed, accompanied by the absence of a break date in the annual rainfall series.
• Seasonal and monthly rainfall trends exhibited significant irregularity, changing from one season/month to another.
• A non-significant increase in rainfall was reported during the autumn season.
• A significant decrease in rainfall was reported during the spring season.
• These trends are explained by the intensity of thunderstorms during the summer season, followed by occasional winter drought.

Contributions

• Provides a detailed statistical analysis of interannual and intra-annual rainfall trends for Khénifra National Park, a significant pastoral mountain area.
• Identifies specific seasonal irregularities and a generalized annual decrease in rainfall, offering insights into regional climate change impacts.
