What it's about:
Two studies within the last month have shown that hurricanes and tropical cyclones are moving at a much slower speed than in previous decades.
The research also found that warming temperatures as a result of climate change will slow the pace even further.
Data from 1949 until 2016 found that tropical cyclones slowed their movement by 10 percent, with some even decreasing by up to a third.
The National Center for Atmospheric Research used climate models to simulate future cyclone scenarios. They found that under a 5 degree temperature increase, rainfall increased by 24 percent.
Why it's noteworthy:
As temperature continues to rise and climate worsens, the rate at which hurricanes and cyclones slows will increase.
Slow movement of these hurricanes means that intense rainfall lingers for a longer period, increasing the chances of extreme flooding. It also increases the length of time that people are subject to strong winds and creates vulnerabilities from storm surges.
This will have serious implications for urban infrastructure, especially in regions with poor flood defenses.
Although the research methods were different - one focusing on historical data and one using climate models for future prediction - the outcomes were very similar. This therefore increases the likelihood of extreme weather events in the coming years.
