Discuss how a warming planet may affect storms in the future. What will be an ideal response?
As the temperature of the atmosphere increases, the capacity to hold water increases,
leading to stronger storms and higher rainfall amounts. Is there a connection between
the warming ocean and the increasing intensity of tropical cyclones? Although the
number of storms has remained relatively constant over the past 35 years,
meteorologists have reported a striking 80% increase in the abundance of the most
powerful (Category 4 and 5) tropical cyclones in the past 35 years. Mathematical
models suggest there is a relationship between the warming climate and
intensification of tropical cyclones. In addition, dust storms in the distant Sahara
desert may also play a role in the development of strong storms. Dust in air acts as
condensation nuclei for raindrops, accelerating their formation and speeding the
release of latent heat. Layers of dry, dusty air blowing westward into the tropical
Atlantic appear to influence the intensity of tropical cyclones. As Earth warms and
deserts spread, this influence could grow
