Weather Statistics for Annular Solar Eclipse of 2003 May 31

Key to Table 1.16

Percent Frequency of Clear, Scattered (2-4 tenths), Broken (5-9 tenths) and Overcast or Obscured Skies
These data are compiled from surface observations at the site. The time of the observation is usually 0300 UTC except for a few stations where observations at that time are missing. This is about one hour before the eclipse.
Probability
A rough calculation of the probability of seeing the eclipse based on the frequency of clear, scattered, broken or overcast cloud. It is essentially the sums of the frequency of the cloud category times a representative clear sky amount for the category.
% hours with cloud <0.3 and vis > 2
This the frequency of hours with less than 3 tenths cloud and visibilities of 3 miles or more. The time of observation is 0300 UTC except for a few cases as noted above.
Monthly pcpn
Average May precipitation in mm. Snow is melted and the water content measured.
% of observations with precipitation
The percent of observations at 0300 UTC in May in which precipitation is reported.
% of observations with fog
The percent of 0300 UTC observations with visibility less than 3 miles.
Mean wind
The average wind speed in May at 0300 UTC
Prevailing Direction
The most frequent wind direction. Where winds do not show a dominant direction, ÒvrblÓ (variable) is shown. If calm winds are the most common condition and more than 20% of observations, ÒcalmÓ is indicated.
Tmax
Mean daily high temperature (°C) for May.
Tmin
Mean daily minimum temperature (°C) for May.
