Can we modify hurricanes?
There have been several suggestions on how humans might modify the intensity or path of a hurricane.
One method suggested was to change the “energy budget” of the environment around the storm. It was suggested that this could be done by dispersing, from aircraft, carbon soot. That soot would absorb solar energy and warm the atmosphere, which would enhance the evaporation of ocean water and promote the formation of thunderstorms. Continue reading
Why are there so few hurricanes every year?
We are about five weeks away from the climatological peak of the hurricane season, which stretches from early June to November.
During that period, even in a particularly active year, not many hurricanes actually develop. Forming over tropical oceans ensures that warm sea-surface temperature (SST) provides a mature hurricane with a means to warm and moisten the air that flows toward the important eye-wall convection. Thus, it is not surprising that hurricanes struggle to develop if the SST is not 79.7 degrees or warmer. Continue reading
Is that photo of circular lightning?
When we see a flash of lightning, it looks as though it forms all at once.
However, a lightning bolt is actually produced in many steps. The bolt occurs so quickly that it looks like a single brilliant flash, but high-speed photography can reveal several distinct bolts. Continue reading

Do cell phones network with weather forecasts?
Cell phones do not directly interfere with weather forecasts. However, there is concern with how cell phone signals travel through the atmosphere, particularly the 5G network.
The 5G technology is designed to carry more data and make wireless connections faster. Continue reading

What is the Beaufort scale?
The Beaufort scale is a method of estimating wind speed based on the general condition of the surface of a large body of water with respect to wind waves and swell.
It is based on observation of sea state rather than accurate wind measurements. This scale allows sailors to estimate the wind speed just by observing the state of the sea surface. Continue reading
