A REDDISH-BROWN SNOWFALL

Multiple firm, reddish-brown papules and nodules on shoulder and arm

Community structure of microorganisms associated with reddish-brown iron-rich snow.

Reddish-brown colored snow, containing spherical brown particles, has been observed in several mires in Japan. In order to characterize this remarkable phenomenon, the microbial community and chemical species in snow were analyzed. A core sample of snow which had a colored region was investigated and it revealed vertical shifts in physicochemical characteristics and the microbial community stru...

Multiple confluent reddish nodules

A 48-year-old fisherman from Amazonas (north of Brazil) developed a small papule on the anterior left leg after a traumatic injury with a piece of wood 20 years ago. Over the course of years, multiple large, confluent, reddish to brownish nodules with eventual ulceration came into being on the left leg and extended to the left thigh. There was a solitary, domed-shaped nodule on the right arm (F...

Snowfall in High Southern Latitudes

based upon t(h)•e atmospheric water balance equation pr vide seasonal precipitation amou ts for areas l rger than I xl km 2. For broad-scale studies in the continental interior net snow accumulation closely approximates precipitation. Annual precipitation is relatively high over the marginal ice slopes in relation to amounts in the interior. This meridional distribution is due to the orographic...
