Explanation:
Sunshine
hours - the average number of hours per day in March with
bright sunshine.
Percent of
possible sunshine: The number of sunshine hours (described
above) divided by the number of hours from sunrise to
sunset at mid-month.Where independent values of the
percent of possible sunshine are available, that value is
given in the table. This statistic is one of the best
measures of the probability of seeing the eclipse as it
includes situations in which the sun may be shining
through a thin cloud cover.
Percent
frequency of (clear, scattered, broken, overcast and
obscured) skies. While observing practices vary slightly
from country to country, clear skies are those free of any
cloud, scattered cloud is from 1 to 4 eights of cloud
cover, broken ranges from 5 to 7 eights, and overcast and
obscured conditions represent 8 eights of coverage. This
cloud cover is the fraction of the sky covered by any
cloud, not just opaque cloud. A sky may have broken cloud
that is completely transparent (high level cirrus for
instance). As such, the cloud statistics are pessimistic
and almost all locations in the globe will have better
eclipse weather than these columns imply.
Probability
of seeing the eclipse: A simplistic calculation of the
chances of seeing the eclipse based on a mean value of
cloud cover for each category and the frequency of
occurrence of the cloud. This column should be used to
compare one site to another rather than as an absolute
indication of success.
Percent of
obs(ervations) with rain at eclipse time: the percent of
time at which precipitaton was reported at the station.
Observations are available at three hour intervals and the
closest interval to the time of the eclipse was selected
for the table.
Percent of
obs(ervations) with TRW at eclipse time. TRW is the
international code for thundershowers. Thundershowers, or
any precipitating convective cloud, would not be expected
to dissipate during the eclipse cooling.
Percent of
obs(ervations) with obstructions to visibility at eclipse
time. These obstructions include smoke, haze and dust but
not fog.
