What is the effect of changes in rainfall in tropical and tropical regions on global climate change?
Changes in tropical rainfall have direct social connections and cause climate change worldwide through teleconnections. Convective precipitation occurs when sea surface temperature (SST) exceeds a threshold, SSTthr, which is usually fixed in time and space. Our 40-year monthly observations show that we find that SSTthr varies by up to 48°C. In space and with season based on the local convective instability, we develop a quantitative theory that is largely SSTthr variations using the climatological state of the tropical atmosphere. Although it is often assumed that the spatial variation of tropical upper troposphere temperature is small and can be neglected, low climatological values have been shown to favor lower SSTthr. Similarly, a small increase in climatological surface relative humidity also leads to its decrease, or climate changes in tropical rainfall should include high temperatures and near-surface humidity and temperature in addition to SST, and need to be better understood. of what controls their distribution in space and time. in conclusion ; It has a great impact on global climate change.
Changes in precipitation in tropical regions play a significant role in the global climate system, as such precipitation is influenced by a variety of factors, including atmospheric circulation patterns, variations in sea surface temperature, the presence of climate phenomena such as El Niño and La Niña, and changes in atmospheric humidity patterns.
Changes in the pattern or alterations in the regime of tropical precipitation can have cascading effects throughout the global climate system. For example, reduced precipitation in tropical areas can lead to changes in atmospheric circulation patterns, affecting the distribution of heat and moisture on a global scale, thereby significantly influencing the formation of cloud systems and the occurrence of extreme weather events in other parts of the world.
Furthermore, they can have significant consequences for tropical ecosystems, affecting biodiversity, flowering and fruiting patterns, and the availability of water resources for local communities.
Therefore, the observations presented in your question, considering a specific location, demonstrate variations in the mechanisms that control changes in tropical precipitation, which in my view, is of paramount importance for predicting the impacts of global climate change and developing effective adaptation strategies.
