Spatial dynamics and consistency of agroclimatic trends in Chile during 1985-2015 to the Köppen- Geiger climate classification

The Köppen-Geiger classification is one of the most common climate systems in world. It allows classifying ecosystem distribution based on temperature and precipitation, two critical factors climate, vegetation cover’s sensitivity. We analyzed dynamics spatial consistency agroclimatic variables each type Köppen- Geiger present Chile, visualizing variables’ behavior throughout territory. Thus, we computed trends different meteorological station, mapping their slope statistical significance, comparing sense among all those that belong to same zone. Our global analysis showed a thermal amplitude decrease northern central areas about 12.03% 20.3%, respectively, an increase south southern 13.7% 26.3%. A generalized frost events (2.90%-16.02%) took place mainly country’s part. Results higher concordance percentages stations belonging B (dry climate) C (temperate climate). maximum occurred from north-central zones, minimum north zone, highlands (700-4000 m a.s.l.), central, south, zone country. Also, precipitation decreases increased roughly Coquimbo Region Variations indices’ can affect yield production crops; thus, information presented here support zoning selection cropping system.
