Total rainfall at a particular location varies with the forward speed of the hurricane, with the size of the hurricane's wind field, and with how vigorous the updrafts are in the hurricane's eyewall.
Hail forms when strong currents of rising air, known as updrafts, carry droplets of water high enough that they freeze.
When updrafts form along cold or warm fronts, hail particles and ice crystals become electrically charged and separate, with ice crystals high in the cloud taking a positive charge and hail particles closer to the ground taking a negative charge.
Previous work has shown that the cloud-top reflectance in the near-infrared increases in middle-latitude, deep-convective overshooting tops--the overshooting tops appear lighter than the surrounding glaciated clouds due to smaller ice crystals (2-4 [micro]m in effective radius), which are frozen nearly instantaneously in intense thunderstorm updrafts. With imagery from GOES-16, the first operational GOES-R series satellite, we find the opposite is true for overshooting convection in the tropics.
When we have paired active updrafts and downdrafts within a thunderstorm, we classify the storm as mature.
"Gulls can use updrafts to increase altitude so they don't have to flap their wings as much to conserve energy.
Like a tornado, a waterspout consists of a low-pressure central vortex surrounded by a rotating funnel of updrafts.
Updrafts lift water droplets into the clouds, where they attract other droplets and freeze together, scientists say.
Like other eagles (there are 59 species of eagles found on every continent except Antarctica), the American Eagle can gracefully soar in the air for hours using natural wind currents and thermal updrafts as earlier mentioned.
For claims, the figures have been super-tight since the 45-year low of 216k in the January BLS survey week, which will probably be breached at some point by mid-year given emerging updrafts from tax reform and spending related to the budget bill that will fill the void of diminishing disaster rebuilding.
When it gets hot enough, air tends to move upward in what is called an updraft. If rain falls and the updrafts are especially strong, water droplets get suspended in the air.
