Why It Matters: At the birth center for climate forces that
affect weather around the globe, scientists found new information that increases the usefulness of climate measurements.
The report, written and reviewed by leading U.S. scientists as part of the National Climate Assessment, reinforces that warming temperatures and
extreme weather around the globe are «extremely likely» to be the result of carbon pollution from human activities.
Climate modellers need to understand the physics of these clouds if they are to correctly work out
how weather around the globe will change as the polar regions warm.
While El Niño is a cyclical climate phenomenon in the Pacific Ocean — marked by warmer ocean temperatures in the tropics and a weakening of the usual easterly trade winds — it can
impact weather around the globe.
And just as heating anomalies in the tropics can
influence weather around the globe, large heating anomalies in the Arctic basin may have ripple effects at lower latitudes, especially across the industrialized countries and population centers of the Northern Hemisphere.
Admittedly, the
warm weather around the globe is a little scary: a city in northern India shattered the national heat record last week, registering a searing -LSB-...]
The disruption to that wind pattern can reverberate through the atmosphere, impacting the flow of air from the equator to the poles, which in turn can affect the jet stream and
weather around the globe.
While El Niño is a cyclical climate phenomenon marked by unusually warm waters in the eastern tropical Pacific, it can affect
the weather around the globe because it alters the transfer of heat from the ocean to the atmosphere.
«These movements cause a massive reorganisation of the atmosphere circulation, leading to extreme climate and
weathers around the globe.
