  • The operational meso-scale short range NWP system was developed for Cheju Regional Meteorological Office located at Cheju island, Korea. The Central Meteorological Service Center, KMA has reported the information on numerical weather prediction every 12 hours. But this information is not enough to determine the detail forecast for the regional meteorological office because the terrain of the Korean peninsula is very complex and the resolution of the numerical model provided by KMA headquarter is too coarse to resolve the local severe weather system such as heavy rainfall. LAPS and MM5 models were chosen for three-dimentional data assimilation and numerical weather prediction tools respectively. LAPS was designed to provide the initial data to all regional numerical prediction models including MM5. Synoptic observational data from GTS, satellite brightness temperature data from GMS-5 and the composite reflectivity data from 5 radar sites were used in the LAPS data assimilation for producing the initial data. MM5 was performed on PC-cluster based on 16 pentium CPUs which was one of the cheapest distributed parallel computer in these days. We named this system as Halla Short Range Prediction System (HSRPS). HSRPS was verified by heavy rainfall case in July 9, 1999, it showed that HSRPS well resolved local severe weather which was not simulated by 30 km MM5/KMA. Especially, the structure of rainfall amount was very close to the corresponding observation. HSRPS will be operating every 6 hours in the Cheju Regional Meteorological Office from April 2000.

  • The present study investigated the quality characteristics of Perilla frutescens Britt. seed compounds according to the cultivar and sowing dates. In the present experiment, five Perilla cultivars, namely 'Dayu', 'Deulsaem', 'Deulhyang', 'Baekjin', 'Sodam', were planted on three different dates, including May 30, June 20, and July 10. The contents of key compounds and phenols varied depending on the cultivar and sowing date. With the delayed sowing time, the days to flowering and maturity of the culitvar decreased, while the seed weight and hardness increased. Crude protein content increased but crude lipid content decreased with the delay in the sowing time. However, there was no interaction of different sowing dates with the fatty acid content, which remained stable compared with the other values. Overall, the total polyphenol content was higher in Perilla seeds sown on May 30.
