Downrange impacts



Downrange impacts

Calculations will probably always be more an imprecise art than a precise science

A large factor is the weather in the area and even the world for some events.  The season also affects the monsoon winds in many places.
The idea applies to both objects, like an arrow or bullet or airplane, and an event, like a volcanic eruption or a nuclear anything.
One can either trust the calculations and plan on them, or just wait and see what happens where they live.
The weather is often “in layers”. Practically that means one layer might be blowing one way at such and such a speed, and another layer is different.
Depending on many factors, there is often a delay factor in effects. Keep that in mind, too. In the 1950’s movie On The Beach the delay factor was in a year or more.
In 1991 the eruption of the super volcano Mount Pinatubo in the Philippines later resulted in some beautiful red and orange sunsets in the new world USA, so the impact can be worldwide if that is a believable example.
Often the weather people “fly” weather balloons at around a 4 hour interval.  For weather junkies, when one sees the many arrows and lines on weather maps, they often come from these weather balloons data, in the end. All this affects downrange impacts and impact forecasts and maps. Later the real data will produce even better maps and graphics.
