Dust Storm

On December 13-14, 2003, there was a dust storm to the East over Iran and Southern Asia. (satellite image).

The Nashi wind (also N'aschi) responsible for the dust storm also affected Dubai in the United Arab Emirates during the same time frame (ref). The winter Nashi wind carries dust storms through the straits and along the coast of Iran. Dust storms can interfere with electronics and distort navigational systems. Also see Shamal Wind below.

Context


Sun, Moon and Weather data must seem like truly petty information. But, the data provides some context that's easy to overlook.

First: there was a full moon on October 10, 2003. As a result, 'lighting conditions' were pretty much as optimal as they could be for conducting a night time search for Kirk von Ackermann. In addition, just two days prior, curfew hours were changed, adding an extra hour to be outdoors after sunset.

Second: east of Iraq, there was a dust storm over Southern Asia December 13-14. Did the storm have any impact on Iraq? Was there more dust than usual in the air? If yes, how did the dust on the vehicle of Ryan Manelick's assailant(s) compare to other cars at the time? More, less, the same?

In an email to Ryan Manelick's father, Greg, John Dawkins described the assailant(s) as driving a 'nice white Land Cruiser.'

Did 'nice' actually refer to 'clean' and did this mean the assailant(s) vehicle was relatively dust free? And if it was dust-free, why? What does a clean vehicle at the moment of attack say about where the vehicle was kept, how far it was driven to the point of attack, and what does it say about the person(s) who were driving it?

Things to think about.

Or not.
