The effect of the Southern Alps on the climate east of the mountains is that they act as a barrier, protecting the area east from the prevailing west winds. This results in the central and eastern areas being cooler and wetter due to the Southern Alps blocking the flow of warmer air from the west and trapping moisture-laden air on the eastern side. This can lead to increased precipitation and cooler temperatures in the eastern areas. Additionally, the snow and ice on the Southern Alps have a chilling effect that contributes to the cooler climate in the east.
