“…The impact of topography on landfalling TCs is more significant than roughness variation, especially in mountainous areas (Chang 1982). Observations (Brunt 1968;Hamuro et al 1969) have confirmed that high correlations exist between the areas of maximum rainfall during TC landfall and the mountainous terrain of the region. Brand and Blelloch (1974) found that topographical effects, if not properly accounted for, can cause significant errors in the forecasting of a TCs motion.…”

This is the second paper of a two-part series of papers on the analysis of tropical cyclone (TC) tracks in the western North Pacific Ocean. In this paper, TC landfalls in the South China Sea and western North Pacific basins are investigated through the data-mining approach. On the basis of historical TC archives, the C4.5 algorithm, a classic tree algorithm for classification, has been employed to quantitatively discover rules governing TC landfall. A classification tree, with 14 leaf nodes, has been built. The path from the root node to each leaf node forms a rule. Fourteen rules governing TC landfall across the Chinese coast have been unraveled with respect to the selected attributes having potential influence on TC landfall. The rules are derived by the attributes and splitting values. From the classification tree, split values, such as 27°N latitude, 130°E longitude, 141°E in the west extension index, and 0.289 in the monsoon index have been shown to be useful for TC forecasting. The rules have been justified from the perspective of meteorology and knowledge of TC movement and recurvature (e.g., deep-layer mean winds and large-scale circulation). The research findings are also consistent with existing results concerning TC movement and landfall. Both the unraveled rules and the associated splitting values can provide useful references for the prediction of TC landfall over China. .J structure, mtenstty, and motion of the TC will change two-part paper, troptcal cyclone (TC) recurvature and ,

SCOPE OF RECENT TROPICAL METEOROLOGY In the past few years we have witnessed a tremendous expansion of the scope of tropical meteorology. Advances in satellite technology and numerical simulation of the global general circulation have made it impossible to maintain the isolation of this classical branch of meteorology from the rest of the atmospheric sciences. During the years 1971-1974 the data obtained by many pre-Garp experiments became available for scientific analysis. The experiments include the Line Islands Experiment (Lie) in 1967, the Florida State University Barbados Experiment in 1968, the Atlantic Trade Wind Experiment (Atex) and the Barbados Oceanographic and Meteorological Experiment (Bomex) in 1969, and the Venezuelan International Meteorological and Hydrological Experiment (Vimhex) in 1969 and 1972. The data from these experiments prompted especially studies of the structure of trade wind subcloud layer. After long international planning the Garp Atlantic Tropical Experiment (Gate) was finally put into operation during the summer of 1974. Its scientific objectives are stated in the Experiment Design Proposal for the Gate [Kuettner et al., 1972] and in an article written by members of the International Scientific and Management Group (ISMG) for Gate [Kuettner et al., 1974]. The central objectives of the Gate are (1) to provide a means of estimating the effects of smaller tropical weather systems on the large-scale circulations and (2) to advance the development of numerical modeling and prediction methods. The ISMG issued the central program document [Houghton, 1974] as well as the radiation subprogram [H. Kraus, 1973], the boundary layer subprogram [Hoeber, 1973], the synoptic scale subprogram [Houghton and Parker, 1974], the convection subprogram [Rodenhuis and Betts, 1974], and the oceanographic subprogram [Philander et al., 1974] documents. These documents contain brief summaries of scientific backgrounds and objectives and observational strategy to achieve the overall goal of the Gate. The Gate was the largest international undertaking meteorologists had ever experienced: 40 ships, 13 aircraft, the SMS geostationary satellite, and several U.S. and USSR orbiting satellites were used. Many U.S. scientists contributed to the planning, implementation, and execution of the Gate. In turn the Gate greatly stimulated tropical research, especially in the fields of parameterization of cumulus convection and the planetary boundary layer (PBL). While the vast number of data gathered by the Gate are being processed, the planning of the First Garp Global Experiment (FGGE) and the Monsoon Experiment (Monex) is already in progress. There will be renewed interest in planetary scale tropical motions and in one of the least explored areas of tropical meteorology, monsoons. We have 685 already seen a substantial increase in the number of research papers on monsoon-related problems. This article will review a variety of topics in tropical meteorology, ranging from the air-sea interaction to the mesospheric oscilla...

Six Decades of Tropical Meteorology Research—A Retrospective on Michio Yanai’s Life and Career

This monograph on convection-coupled systems in the tropics was inspired by the life and career of Professor Michio Yanai, whose major contributions to the subject spanned more than five decades. From a distant perspective, Professor Yanai’s career can be understood in the context of Japanese scientists who immigrated to the United States in the decades of the 1950s and 1960s, enriching the meteorological research community in the United States as well as abroad (Lewis 1993). A closer look reminds us that the tapestry of scientific progress is created by the contributions of individual scientists with their unique backgrounds, motivations, and talents, and the serendipity of events that shape their lives.
