An air burst or airburst is the detonation of an explosive device such as an anti-personnel artillery shell or a nuclear weapon in the air instead of on contact with the ground or target. The principal military advantage of an air burst over a ground burst is that the energy from the explosion, including any shell fragments , is distributed ...
Airburst effect from 40mm round on dummy soldiers. An airburst round is a type of tactical anti-personnel and anti-aircraft explosive ammunition, typically a shell or grenade, that detonates in midair, causing air burst effect fragment damage to enemy personnel or aircraft (notably comparably unsophisticated unmanned aircraft systems such as modified racing drones).
A meteor air burst is a type of air burst in which a meteoroid explodes after entering a planetary body's atmosphere. This fate leads them to be called fireballs or bolides , with the brightest air bursts known as superbolides .
An air burst produces a relatively small amount of the highly radioactive heavy metal components of the device itself. In case of water surface bursts, the particles tend to be rather lighter and smaller, producing less local fallout but extending over a greater area.
In either scenario, an air burst or a direct impact, 2024 YR4 could lay a good-sized city to waste if it were unlucky enough to be in the crosshairs. An impact could be a world-changing calamity.
A fuel–air explosive (FAE) device consists of a container of fuel and two separate explosive charges. After the munition is dropped or fired, the first explosive charge bursts open the container at a predetermined height and disperses the fuel in a cloud that mixes with atmospheric oxygen (the size of the cloud varies with the size of the ...
As the cold air hits the ground or water it spreads out and a mesoscale front can be observed as a gust front. Areas under and immediately adjacent to the downburst receive the highest winds and rainfall, if any is present. Also, because the rain-cooled air is descending from the middle troposphere, a significant drop in temperatures is noticed.
A quick but intense blast of Arctic air will barrel into the Northeast later this week to deliver quite a cold shock to the Northeast and neighboring Canada, AccuWeather meteorologists warn. The ...
