Incidence of malaria cases and main environmental components, shifted according to cross-correlation lags. The black line represents malaria incidence (%), the green line, evaporation/rainfall component (Met1, 12 weeks lag), the red line, temperature component (Met2, 13 weeks lag), the dark red line, temperature variation component (Met3, 5 weeks lag), the blue line, river height component (Riv1, 6 weeks lag), the light blue line, the first river height variation component (Riv2, no lag), the cyan line, the second river height variation component (Riv3, 7 weeks lag)
