Unalaska has a record of extreme cloudiness for one whole month, February, 1880.
Sir J. C. Ross, an Arctic explorer, recorded a shower of nearly an hour’s duration on Christmas day, 1839, without a cloud in sight.
A similar record was made on June 30, 1877, at Vevay, Ind., where a shower lasted for five minutes in a cloudless sky.
A fall of yellow snow was recorded at South Bethlehem, Pa., in 1889. Examination showed this coloration to be due to the pollen of the pine trees which had been blown into the atmosphere before the fall.
Another record of yellow rainfall was recorded at Lynchburg on March 21, 1879.
Golden snow was recorded at Peckoloh, Germany, in 1877.
Green and red snows have been observed during Arctic explorations, due to a minute organism that was in the atmosphere.
When the temperature of the atmosphere is nearly 32° during a snow storm and the wind is blowing, the flakes being damp and the snowfall heavy, the flakes are apt to unite to form large masses of snow in the atmosphere or air, which accounts for some of the following records:
At Chapston, Wales, in January, 1888, the snowflakes measured 3.6 inches in length and 1.4 inches in breadth, and 1.3 inches in thickness. They amounted to 2½ cubic inches of water when melted.
There are some remarkable instances of where hailstones have cemented together, making large masses of ice. Some remarkable records of this kind have been recorded in India.
