90 -day forecasts, although these are
not as specific as the day to day fore-
cast, and I think we will see slow
improvements in that type of long-
range forecast in the next ten years.
In the next five years, though, we will
start to see a better deliniation of the
differences within what is now con-
sidered the same forecast area.
"We e may expect some
showers of rain this
month or the next, or
the next after that, or
else we shall have a
very dry Spring.'
— March forecast from
Poor Robin's Almanac,
1664
For example, in the TV -London
viewing area there are distinctive
weather belts, and we will be able to
do a better job in our five-day forecast
to point out those differences before
we get into the 1990s. We will be as
accurate on that five-day forecast —
and in deliniating that forecast — as
we now are with our two-day forecast.
And that will mainly come about
because of the increasing speed of
computers."
§§§
As an occasional lecturer at
Centralia College of Agricultural
Technology, Campbell believes that
more colleges should offer weather
programs to agricultural people, and
suggests that even small agricultural
associations could benefit farmers by
sponsoring one -day weather seminars.
