Convective precipitation events (thunderstorms) tend to produce shorter duration storm events than orographic precipitation. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall. Most precipitation in the area is orographic precipitation. Precipitation induced by orographic lift occurs in many places throughout the world. This process of orographic enhancement leads to higher precipitation than surrounding areas. One could still hardly speak of dense topographic, orographic and hydrological information. Their proximity to the ocean and through orographic effect, they receive high rainfall. The major part of the rainfall at Sohra can be attributed to the orographic features. It is often associated with orographic lift caused by the escarpment. In meteorology this is known as orographic lift. The course of the Sava River runs through several diverse geological units and orographic regions. Surface air circulation is largely influenced by orographic lift. Additional discrepancies caused by orographic variation at specific locations can be significant. Orographic lift causes brief but strong afternoon thunderstorms during the summer. Orographic lift occurs as air masses rise to pass over high ground.
