Mauna Loa has a tropical climate with warm temperatures at lower elevations and cool to cold temperatures higher up year-round. Below is the table for the slope observatory, which is at in the alpine zone. The highest recorded temperature was and the lowest was on February 18, 2003 and February 20, 1962, respectively.
when was the last time mauna loa volcano erupted March 24 to April 15, 1984. what is the main entity? It is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaiʻi in the Pacific Ocean.
Mauna Loa has a tropical climate with warm temperatures at lower elevations and cool to cold temperatures higher up year-round. It has a tropical climate with warm temperatures at lower elevations and cool to cold temperatures higher up year-round. Trade winds blow from east to west across the Hawaiian islands, and the presence of Mauna Loa strongly affects the local climate. At low elevations, the eastern (windward) side of the volcano receives heavy rain; the city of Hilo is the wettest in the United States.

Mauna Loa has a tropical climate with warm temperatures at lower elevations and cool to cold temperatures higher up year-round. Trade winds blow from east to west across the Hawaiian islands, and the presence of Mauna Loa strongly affects the local climate. At low elevations, the eastern (windward) side of the volcano receives heavy rain; the city of Hilo is the wettest in the United States. The rainfall supports extensive forestation. The western (leeward) side has a much drier climate. At higher elevations, the amount of precipitation decreases, and skies are very often clear. Very low temperatures mean that precipitation often occurs in the form of snow, and the summit of Mauna Loa is described as a "periglacial" region, where freezing and thawing play a significant role in shaping the landscape.
