Worked Solution & Example Answer:Exchanges of water between ocean and atmosphere vary over the surface of the earth and this gives rise to distinctive weather conditions - Leaving Cert Geography - Question 22 - 2011
Step 1
Aspect 1: Evaporation and Precipitation
Answer
The exchange of water through evaporation from the ocean and subsequent precipitation over land is a core process. For example, in tropical regions, high temperatures increase evaporation rates, contributing to heavy rainfall patterns such as those observed in the Amazon rainforest. This cycle not only shapes local weather but also affects global climate systems.
Step 2
Aspect 2: Ocean Currents
Answer
Ocean currents play a crucial role in the redistribution of heat and moisture across the globe. The Gulf Stream, for instance, warms the eastern coast of North America and affects weather patterns significantly, leading to milder winters in regions such as the UK. The interaction between warm and cold currents also influences storm development, contributing to the occurrence of hurricanes in the Atlantic.
Step 3
Aspect 3: Regional Variations
Answer
Different regions experience distinctive weather conditions based on their geographic location and the surrounding water bodies. For instance, coastal areas often have milder climates due to the moderating effect of the ocean, while inland regions can experience extreme temperatures. The impact of the Mediterranean Sea on the climate of Southern Europe, resulting in hot, dry summers and mild, wet winters, exemplifies this phenomenon.
