Monsoons: Wet, Dry, Repeat… 

The monsoon is a seasonal rain and wind pattern that occurs over South Asia (among other places). Through NASA satellites and models we can see the monsoon patterns like never before. Monsoon rains provide important reservoirs of water that sustain human activities like agriculture and supports the natural environment through replenishment of aquifers. However, too much rainfall routinely causes disasters in the region, including flooding of the major rivers and landslides in areas of steep topography. This visualization uses a combination of NASA satellite data and models to show how and why the monsoon develops over this region. In the summer the land gets hotter, heating the atmosphere and pulling in cooler, moisture-laden air from the oceans. This causes pulses in heavy rainfall throughout the region. In the winter the land cools off and winds move towards the warmer ocean and suppressing rainfall on land.

Earlier Severe Weather Warnings 

Early warning is key in any severe weather forecast. Meteorologists at the NOAA National Severe Storms Laboratory (NSSL) in collaboration with the University of Oklahoma School of Meteorology have developed the Collaborative Lower Atmosphere Mobile Profiling System (CLAMPS). CLAMPS is a trailer full of instruments that measure air temperature, humidity, and the wind.

According to David Turner, a meteorologist with the NSSL, the goal is to create rapid forecasts that can tell scientists and the public what the weather conditions will be like in the next 30 minutes to one hour. “We’d like to be able to issue a warning based on a forecast that would lengthen our ability to give warnings by 10-20 minutes that could be extremely beneficial in saving lives.”

What Makes Fresh Air Fresh? 

There’s nothing like the crisp fresh air of a spring morning, especially compared to the musty weird air in your smelly old house… But why is the air outside so much more pleasing? And can you make inside-air just as fresh and nice?

The Science of Sunset Colors 

We all enjoy beautiful, multicolored sunsets. But what causes the brilliant oranges, pinks and purples that we see, and why does it change from day to day and season to season?
