Question
Explain the effect that the southern acts on the climate east of the mountains
There’s snow and ice have a chilling effect, keeping the central and eastern area is cool and wet
They divert precipitation into the east area, creating monsoon conditions
They add as a barrier, protecting the area east from the prevailing west winds
Their presence intensifies the speed of the roaring 40s

The Southern Alps, located on the South Island of New Zealand, have a significant impact on the climate of the area east of the mountains. Here’s a breakdown of how they influence the climate:
1. **Snow and Ice Influence**: The presence of snow and ice on the Southern Alps results in cooler temperatures in the surrounding regions. The high altitude of the mountains leads to a phenomenon known as orographic lift, where moist air is forced to rise over the mountains. As it rises, it cools, leading to precipitation. As a result, the areas to the east can remain relatively cool and wet compared to those on the western side.
2. **Precipitation Patterns**: The Southern Alps act as a barrier for moist westerly winds that bring precipitation from the Tasman Sea. This causes the western side of the mountains to receive heavy rainfall (often resulting in lush forests), while the eastern side experiences a rain shadow effect, which can create drier conditions. However, some precipitation is redirected to the eastern regions, contributing to various weather phenomena, including monsoonal-type conditions in certain seasons, where dry spells can be followed by intense rainfall.
3. **Barrier to Prevailing Winds**: As a significant geological feature, the Southern Alps shield the eastern areas from the prevailing westerly winds. This barrier effect means that the region to the east of the mountains experiences more stable weather patterns, with reduced wind and less storm activity compared to the more turbulent weather found on the western slopes.
4. **Influence of Roaring Forties**: The "Roaring Forties" refers to the strong westerly winds found in the Southern Hemisphere, particularly around latitudes 40 to 50 degrees. The Southern Alps can intensify these winds' effects, causing them to accelerate as they funnel through mountain passes or along the lee side of the mountains. This can lead to greater weather variability, including gusty conditions and rapid temperature changes in the areas immediately east of the range.
In summary, the Southern Alps significantly shape the climate east of the mountains through their influence on temperature, precipitation patterns, wind protection, and the dynamics of the Roaring Forties, leading to a unique and diverse climatic environment.
