The Distance Calculator can find distance between any two cities or locations available in The World Clock. Most cloud-to-ground lightning flashes consist of long in-cloud branches that extend outward. The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. Roll clouds are relatively rare; they are completely detached from the thunderstorm base or other cloud features, thus differentiating them from the more familiar shelf clouds. The highest level of cloud will form higher than 7000m high. That having been said, the tops of thunderstorms are high enough to be above most atmospheric haze and dust (higher than any mountain), so as long as the air is pretty clear, one ought to be able to see the tops of them from nearly their mathematically possible distance. ... Take the number of seconds and divide by 5 and that will tell you how far away the storm is in miles. For most purposes we can ignore the curvature of the earth. Objects on the ground generally have a positive charge under a typical thunderstorm. The "Tri-state" tornado of 18 March 1925 killed 695 people as it raced along at 60-73 mph in a roughly 243-mile-long track across parts of Missouri, Illinois and Indiana, producing F5 damage. For a bomb that size, people up to 21 km (13 miles) away would experience flash blindness on a clear day, and people up to 85 km (52.8 miles) away would be temporarily blinded on a clear night. * 0.5 miles/(22 deg.)

Found inside – Page 4However , there are some who feel that the 5 mile parameter is far too conservative , while from the standpoint of others ... of ground discharges occur at the edges of the clouds or from Wispy clouds near the main convective cloud . If this same cloud is one vertical fist by 1 horizontal fist across, then the cloud’s dimensions are both Cloud Dimension = 11 deg. Where I live it is very common to have a ceiling at 1000 or 1500 feet. One reason that planes cruise above the clouds is so they can fly fast. or Cloud Dist. This is most often < 100 miles, but in exceptionally clean and dry atmosphere, it may exceed that distance. = 1.3 miles away. Cloud clearance and visibility requirements for Class D airspace are three statute miles, 500 feet below clouds, 2,000 feet horizontal, and 1,000 feet above. Using a little bit of math and your hands as angle measurers, you can estimate the distance and size of these clouds. Obviously it will vary by the height of the cloud, but a rough idea? The stratosphere is a layer of Earth's atmosphere.It is the second layer of the atmosphere as you go upward. Clouds can come at different altitudes, so you need to find out the current cloud ceiling (how high the bottom of the clouds are). You can also try a different route while coming back by adding multiple destinations. I seriously underestimated the distance of the storms; I thought they were between Fond Du Lac and Milwaukee. Funny thing. This formula calculates the distance from an observer to the horizon, which for a six-foot tall person is close enough. MathJax reference. 1 MILE 5 STATUTE MILES #V MILES VISIBILITY VISIBILITY 1,060’ I FIGURE 5. More relevant to the problem in question is the visibility limit due to light scattering. How can I learn to make mesoscale/synoptic analyses of major weather events? I never realized it was because of a huge shadow until that plane trip. For both types of clouds have a typical average height above the surface or land. These water droplets are kept aloft by the upward currents of air (called thermals). Then it extends to the ground. Therefore, if you want to find out how far you are from lightning, divide the number of seconds by 5 if you want the answer in miles and divide it by 3 if you want the answer in kilometers. I tried to simplify the verbiage & some literal-minded folks might interpret that I was talking about the slant range from the observer to the cloud itself. It's a little thinner at the poles and thicker near the equator, but the "sky" is about 250 miles wide (or up), the distance, roughly, between New York City and Washington, D.C. How many Jimmies does this platform need? The following formulas are used to estimate cloud height and temperature. Wow, that has no definite answer due to the different types of clouds and the various altitudes of each. Even fog, which has no altitude, is a clou...

Earth Science Stack Exchange is a question and answer site for those interested in the geology, meteorology, oceanography, and environmental sciences. High 88F. Aside from obvious visual obstructions like trees, buildings, and clouds, there’s one major factor that can reduce your sightline: the curvature of the Earth. Cloud-to-Air Lightning Referring to a discharge (or a portion of a discharge) jumping from a cloud into clear air. The Bell X … A cloud at 4,000 feet is 1.3 miles away on the ground at 30 degrees. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. It depends both on the type of cloud and on the region of the world; there are three main layers of clouds: - the highest layer is at an altitude o... And at that distance the curvature iof the earth isn’t zero, but it’s a lot smaller than the uncertainly in the other numbers & hence can (& should) be ignored. “The cloud entrains ambient air into it and continues to grow and mix,” Bourouiba says.

This stipulates that commercial airliners traveling Northeast, East, Southeast, and one degree short of South fly at odd altitudes (31,000ft, 33,000ft, etc. ), the Cloud Distance = 57.3 deg. The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. Dust, water vapour and pollution in the air will rarely let you see more than 20 kilometres (12 miles), even on a clear day. Starting Point. So, if lightning strikes the ground 5 miles away, you may hear thunder directly above you after five seconds, meaning that the branches are one mile away (straight upwards), not the … Clouds are formed when moist air cools to its dew point temperature causing water vapour to condense into droplets of liquid water.
