A blizzard is one type of storm that has no scale in which to measure its intensity. Susan Callery. Ice sheets and glaciers on Greenland and Antarctica hold much of our planet's land ice. Jet Propulsion Laboratory, Pasadena, Calif. How do blizzards affect the geosphere? In late February, as the Southern Plains and Gulf Coast suffered through an unusually strong blast of wintry weather, weather talk turned to the polar vortex and the possibility that the extreme cold was yet another example of weather-gone-wild due to global warming. This water also provides an important source of hydroelectric power. Ice and winds cause trees to fall and plants to die. The data is freely accessible and can help assess reefs around the world. For example, disruptions of the polar vortex occur when the vortex is bumped from below by large-scale atmospheric waves flowing around the troposphere, said Butler. Among the possibilities is that the polar vortexs preferred location may be sensitive to regional variations in sea ice cover. These observations help us better understand and prepare for the effects of human-caused global warming. As part of NASAs Oceans Melting Greenland mission, which surveys glaciers with aircraft and ships, scientists want to gain a better understanding of how ocean warming affects coastal glaciers. Not to mention, sometimes the polar vortex is disrupted and there are few, if any, impacts on the weather down at the surface. Screen capture from Earth.Nullschool, based on NOAA Global Forecast System data. When the Arctic polar vortex is especially strong and stable (left globe), it encourages the polar jet stream, down in the troposphere, to shift northward. Here are some related questions which you might be interested in reading. They can also have positive effects on forests, such as enhanced growth of surviving trees 5 and increased biodiversity 11. Like other currents in the worlds oceans, the Beaufort Gyre plays an important role in regulating massive exchanges of water around the globe with different temperatures and salinity. The polar jet stream made a deep dive into the south-central United States, bringing extreme cold (dark blue) to the Southern Plains. The combined ice losses caused sea levels to rise by 0.55 inches (14 millimeters) over those 16 years. A blizzard can cause lots of property damage, such as roof cave-ins and windows breaking. You Didn't Really Think Winter Was Over, Did You? How do At the other extreme, the polar vortex is occasionally knocked off kilter when especially strong atmospheric waves in the troposphere break upward into the stratosphere. The atmosphere now holds more moisture, and that in turns drives heavier than normal precipitation, including heavier snowfall in the appropriate conditions. Ice can increase the weight of branches by 30 times. Every thunderstorms has lightning but it isnt always visible. NASAs Earth Science News Team. By the time the storm blew offshore on March 14, some Connecticut towns reported snowfall amounts of nearly 50 inches although exact amounts were nearly impossible to measure thanks to the gale-force winds that earned the storm the nickname the Great White Hurricane. Winds of over 60 miles per hour created massive . Either way, these interactions prevent landslides. This happens because when magma erupts into lava, it cools more quickly than it would if it stayed inside the earth, giving crystals less time to form. The gyre then slowly releases this fresh water into the Atlantic Ocean over a period of decades, allowing the Atlantic Ocean currents to carry it away in small amounts.
