for producing these important low-pressure systems, and hence tornadoes. The un-La Niña-ish atmosphere over North America meant that suggesting that the spring tornado season would be active was fraug ...

the weather balloons measure ozone concentrations as they drift up through a column of the atmosphere. Locations where the total ozone concentration falls below 220 Dobson units are considered part of ...

Karin and Friends determined in the last month or so:. * The 4.75" diameter hailstone that fell in Minooka, Illinois, in June 2015 was indeed the largest retrieved and reported in the Illinois record. ...

pressure centers that underwent the rapid intensification that meteorologists call bombogenesis, in which the storm's central pressure drops by at least 24 hPa in a 24-hour period. In addition, 8 of t ...

enhanced convective phase, winds at the surface converge, and air is pushed up throughout the atmosphere. At the top of the atmosphere, the winds reverse (i.e., diverge). Such rising air motion in the ...

history, the town has been visionary in dealing with, and planning for, complex coastal issues. In 2015, Nags Head initiated a comprehensive planning effort with direction from the Nags Head Board of ...

altitude. But…. if you are thinking of the polar vortex as a specific, dynamic feature of the atmosphere that is present on a given day and time, then talking about a "polar vortex reversal" paints th ...

1), so the reason for a delayed temperature response to La Niña likely isn't rooted in the atmosphere. A more likely culprit is the land surface, specifically the soil moisture conditions. When the so ...
