Rain gauge data revealed intensive rainfall (\u0026gt; 80 mm in 100 min) over northwest of Jeju Island, and relatively low rainfall (\u0026lt;= 20 mm) over the northeast of the island. The environment of the precipitation system consisted of near-saturated air (relative humidity (RH): similar to 95%) from the surface to 700 hPa and a low lifting condensation level of 951 hPa. Doppler radar analysis revealed enhancement of the precipitation system on the northwestern lateral side (in this study, the term \u0027lateral side\u0027 refers to the sides of the mountain other than the lee-side and windward side) of Mt. Halla, the central mountain on the island (1950 m). In the region of enhancement low-level convergence (7 x 10(-4) s(-1)) induced by orographic blocking with a relatively low Froude number (0.55) was observed. These observations were well simulated by a control run (CNTL) using CReSS. The simulated precipitation system was enhanced over the northwestern part of the island due to wind passing around Jeju Island, low-level convergence (1.6 x 10(-3) s(-1)) due to orographic blocking, and high RH (similar to 95%). In order to clarify the influence of topography and the low-level moist environment on enhancement of the precipitation system, numerical sensitivity experiments were conducted. The NOTR (no terrain) experiment produced straightforward wind without low-level convergence over the topography. Associated with these features, the CNTL rainfall amount on the northwestern lateral side of the island was 30.6% more than that produced in NOTR. A comparison of RH-controlled experiments and CNTL revealed that increasing moisture in the low-level environment resulted in greater intensity of the precipitation system. A reduction in low-level RH by as little as 2% could result in a 20.8% reduction in rainfall amount. Therefore, land areas with small, narrow, but steep topographic features, such as Jeju Island, could determine the intensity and location of the precipitation system under a moist environment during the rainy season.
