Lots of guessing going on, here is one well documented. from:

This seems to answer one the most often posed questions as to why spraying is so
common, if not outright aggressive, ahead of an in bound weather storm. The two
most important reasons for the spraying ahead of a storm; first the thick contrails
are flown looking for scalar interference immediately ahead of the storms
EXPECTED path, up to several hundred miles ahead. Helical twisting, broken trails,
large evaporating gaps in the trails and vertical/horizontal contrail displacement
reveal how much the atmosphere is being altered (heated/cooled/displaced) ahead
of the storm so the military forecasters get additional direct observational data to
improve their forecasts and know where to 'fight back.' The environment
immediately ahead of a storm is ripe for the development of high cloudiness; with
one of the stated agendas of contrails being solar reflection the pre-storm
environment is an ideal location to do this work. With so many storms putting down
amounts of rain that might cause flooding these drying/moisture-absorbing
mixtures can be flown/injected immediately ahead of the storm front reducing the
intensity of the severe weather attack. This assumes that this battle is fought
between the Eastern and the Western entities. If the Elite has control of all of this,
contrails and the scalar technology, then only one agenda applies, and it is all bad
news if this viewpoint ends up being the way it is. Somebody knows and will tell us
all, I eagerly look forward to that day.
With the chemtrail/contrail marker flights so common in the Western hemisphere
of influence one must then conclude that all governments, that allow these contrail
marker over flights, know of the scalar war being waged in the skies above. This
outright deceit of the public must end. We see these marking flights each and every
day of the year, we now know why they are flown and demand a full accounting of
the activities that occur in our skies. This is a technology, which because it affects
everyone on this planet, rightly belongs to the people. It is readily apparent that
those that have and use the scalar weaponry are incapable of using it for the
betterment of mankind and therefore are not worthy of the leadership positions
they presently hold. When an agenda of greed, thirst for power, deceit and
deception is at the basis of their moral compass a change of leadership is hereby
demanded. Public oversight was attempted with Congressional hearings initiated by
Senator Pell back in the 1970's, but met stiff resistance.

org/enmod/US_Congr.html These guys then slipped back underground to
continue the development of these very powerful weapons. The time has come for
this power over the planets and indeed Creations most basic functions be handed
back to the People. I don't have a problem with controlling the weather; if it
weren't supposed to be done then the process simply wouldn't be possible.
Therefore what must happen is that the intent of these operations must change,
and change to reflect an outcome that leads only to the Highest and Best Good of
All. Any other intent will ultimately result in a planetary catastrophe. Please
contact your Congressional representatives and make them aware of this situation;
as representatives of the government it is their responsibility to be aware of these
activities that are done in our name.
