by Daniel Brouse and Sidd Mukherjee In a vacuum, everything falling to earth accelerates at 9.8 m/s^2 (32ft/s^2) [the downward speed increases at 9.8 m/s (32 ft/s) every second.] Rain accelerates down to earth initially at 9.8 m/s^2, but air resistance slows the drops to a constant speed called the terminal velocity which depends on […]

Record-Setting Rain
On April 29, 2014, the Global Precipitation Measurement (GPM) satellite observed the heavy rain that produced floods near Pensacola, Florida. The National Weather Service reported record-setting rainfall totals of more than 380 mm (15 inches) in Pensacola from the storm system that inundated the southeastern and eastern United States in recent days. This image shows […]

Climate Change in the United States
The U.S. Environmental Protection Agency says: The Earth’s climate is changing. Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events—like heavy rainstorms and record high temperatures—are already affecting society and ecosystems. Scientists are confident that many of the observed changes in the climate can be linked to the increase in […]

Belief in Anthropogenic Climate Change
From the American Meteorological Society A series of polls provides new tests for how weather influences public beliefs about climate change. Statewide data from 5000 random-sample telephone interviews conducted on 99 days over 2.5 yr (2010–12) are merged with temperature and precipitation indicators derived from U.S. Historical Climatology Network (USHCN) station records. The surveys carry […]

Q: Why Did the Sea Level Drop?
A: Because the rain fell on Australia. By Alan Buis, NASA’s Jet Propulsion Laboratory David Hosansky, National Center for Atmospheric Research A unique and complex set of circumstances came together over Australia from 2010 to 2011 to cause Earth’s smallest continent to be the biggest contributor to the observed drop in global sea level rise […]

Large Storm System in Eastern U.S.
National Oceanic and Atmospheric Administration (NOAA) The large storm in the eastern U.S. is visible in the satellite image below, taken by GOES East at 1715Z (12:15 EST) today. The storm system continues to bring significant rainfall to Indiana and Michigan, where Flood Warnings and Advisories are in effect. The bulk of the precipitation has […]
