Rainfall Distribution

Rainfall distribution in Lawang is influenced by topography and prevailing wind patterns. The mountainous areas to the east of the town receive higher rainfall than the lowlands to the west. Additionally, the monsoon winds bring moisture-laden air from the Indian Ocean during the wet season, resulting in heavy rainfall on the western slopes of the mountains. This distribution pattern leads to uneven water availability and agricultural productivity in different parts of the region.

Historical Snowfall Event

Lawang, a town in East Java, Indonesia, experienced an extraordinary weather phenomenon on September 14, 2016, when snowfall was reported in the area. This was a highly unusual occurrence, as snowfall is extremely rare in Indonesia, a tropical country located near the equator. The snowfall was reportedly light and confined to higher regions of Lawang. While the exact cause of the snowfall is still not fully understood, meteorologists speculate that the combination of unusually cold air and high humidity created conditions conducive for snowflake formation.

Possible Explanations

Despite the rarity of snowfall in Indonesia, it is not entirely unprecedented. Similar snowfall events have been recorded in the past, particularly at higher elevations in the mountainous regions of the country. The most plausible explanation for these occurrences is the combination of extreme weather conditions. Cold air masses from the south polar region can descend upon Indonesia during certain periods, bringing with them low temperatures. When these cold air masses interact with the moisture in the atmosphere, they can create conditions suitable for snowflake formation. Additionally, the topography of Lawang, with its higher elevations, may have contributed to the formation of snowflakes.
