Other claims from this paper (8)
- Observation Temperature showed a significant positive trend averaging 0.03–0.04 °C per year and 0.02–0.04 °C per growing season.
- Observation Precipitation in Free State had a decreasing trend of 0.01 mm per year.
- Observation Solar radiation did not show a significant trend.
- Observation Wind speed in Free State increased at a rate of 0.01 ms −1 per growing season.
- Association Maize yield variabilities in Free State, Mpumalanga and North West showed a significant positive correlation (r > 0.43) with agrometeorological variables.
- Observation The leading mode of each agrometeorological variable, explaining 50–80% of total variance, indicates a spatially homogenous pattern across the regions.
- Mechanism The authors suggest that the dipole patterns of the second and third modes show agrometeorological variabilities linked to the South Indian high pressure and the warm Agulhas current.
- Association The corresponding principal components were mainly associated with strong climate anomalies identified as El Niño and La Niña events.
