For thunderstorms and resultant lightning to occur, there must be rising currents of warm, moist air. Deep in the Arctic and Antarctic, there is only cold, dry air, which does not rise, and thus cannot form thunder clouds, says Douglas Herman, senior geographer at theNational ...
Most thunderstorms occur later in the day because in the evening, the ground is at its hottest, following an entire day of sun heating, which causes warm air to rise and meet the relatively cooler air up in the atmosphere, leading to instability. Also, daytime heating enhances the air’s ...
The loud thunder that follows the lightning bolt is commonly said to come from the bolt itself. However, the grumbles and growls we hear in thunderstorms actually come fromthe rapid expansion of the air surrounding the lightning bolt. ... As the heated air expands, the pressure drops, the ...
FEMALE STUDENT: Since you almost always get lightning with thunderstorms, we can pick up VLF waves pretty often, right?You just have to wait until there's a thunderstorm… MALE PROFESSOR: Ah, do you? Have to wait?VLF receivers are very sensitive and VLF mwaves travel very far.So we can...
What does a high blood pressure headache feel like? What are the symptoms of Hypertension Headache? Headaches associated with Hypertension are often describes as; 'pulsating and throbbing' and will often occur in the morning. Why do windy days give me headaches?
These natural waveguides occur when the Sun is rising or setting, which makes sunrise and sunset good times to pick up VLF emissions. Now, there are a few different sounds that you can hear on a VLF receiver, because when lightning strikes the radio waves travel different distances and in ...
Why does orographic rainfall occur? What are some of the effects of a tornado? Why do volcanoes cause lightning? How does wind shear affect thunderstorms? Why do clouds form? Why does inversion happen in meteorology? Why do thunder and lightning usually happen together?
Why does lightning strike? A lightning bolt is a discharge of electricity in the atmosphere. The strike equalizes the positive and negative charges in the air. It usually happens within clouds, but it can occur between the clouds and the ground. Why does thunder come after lightning? 54115341...
As moisture is a key ingredient in thunderstorm development, the more moisture in the air, the higher the chance of thunderstorms and accompanying lightning strikes. Air turbulence There appears to have been a rise in the number of severe cases of air turbulence during recent months. (Image ...
Earthquakes, thunderstorms, lightning strikes, tornadoes, hurricanes, forest fires, and volcanic eruptions can strike anywhere at anytime killing thousands of people at a moment’s notice. And on top of all of the different natural disasters that can occur in this life, we also have to deal wi...
