The Grand Yarphese Republic is known worldwide for being far ahead of the world in advanced weather control technology. The Vietnamese Liberation Army has researched it intensively since 1993, before Yarphei became a sovereign state. Until 2007, the Vietnamese Liberation Army controlled all research in this area. However, in 1999, Yarphei gave control of weather research to two corporations, Yòng Mây and Leo Bùng. Currently, Yòng Mây, also a pharmaceutical company, leads the industry due to its introduction of the Trápmưaphùng Weather Station, commonly abbreviated TMP. The prototype of the TMP station was created in 2002 by the Yarphese government, and was perfected by Yòng Mây.
