“The moon is wading deep in snow,” is one of many sayings people used to forecast weather from the clouds.
Clouds form when moist air rises to a cooler altitude and condenses around tiny particles. Strong winds move the clouds around the world until the water falls as rain or snow.
In 1803, Luke Howard (1772-1864), a British amateur meteorologist, categorized clouds using Latin names. Modern cloud classification is based on his system.
The Latin cloud names describe their appearance. Layer-like clouds are called stratus clouds. Cumulus clouds are piled-up masses of white clouds. Cirrus clouds are curly white clouds.
Stratus and stratocumulus are low-level clouds. Mid-altitude clouds (alto-) are generally found between 6,000 and 20,000 feet. High altitude clouds (cirro-) are generally found above 20,000 feet.
Cumulus and cumulonimbus clouds may reach heights as great as 60,000 feet from their base. Beware when the top of such a cloud flattens out to the shape of an anvil. Then, it’s a thunderhead!
Once, people depended entirely on folklore to predict weather. Today, forecasters may use modern scientific instruments, but they still have to look to the clouds.
National Stamp Collecting Month
On October 1, 1981, the USPS began its very first National Stamp Collecting Month, a celebration that continues to this day.
The USPS and the Council of Philatelic Organizations created National Stamp Collecting Month in 1981. In announcing the annual celebration, then-Postmaster General William F. Bolger encouraged “employees and customers alike to discover the joy of stamp collecting – the hobby of a lifetime.”
That first year, the USPS produced a Souvenir Card picturing two stamps – US #245, the $5 Columbian, and #1918, the 1981 “Benefiting Mankind” stamp from that year’s Space Achievement issue. The theme that first year was “Discover Stamp Collecting – the Hobby of a Lifetime.”
In 1982, another souvenir card was issued, picturing US #C3a, the legendary Inverted Jenny. The 1983 card pictured US #293, the Mississippi River Bridge from the Trans-Mississippi Exposition. The theme that year was “Discover the Beauty and Lore of Stamp Collecting… the Hobby of a Lifetime.” The 1984 card pictured US #2104, the Family Unity stamp, to go with the theme “Fall in Love with Stamp Collecting – A Family Hobby.”
In 1985, the USPS issued its first stamps specifically for National Stamp Collecting Month, picturing different breeds of horses. Ever since they’ve issued a set of stamps most years in early October or late September to celebrate National Stamp Collecting Month. Often, these stamps are geared toward children, to help increase interest in a new generation of collectors.
And whether or not a new set of stamps is issued each year, the USPS and local stamp groups often stage National Stamp Collecting Month events. Many years the USPS has also created special National Stamp Collecting Month cancelations.
