Delineation of boundary between tropical/subtropical in the middle section for eco-geographic system of South China
China ; Climatic index ; Concept ; Ecosystem ; Geosystem ; Soil ; Southern China ; Subtropical zone ; Tropical zone ; Vegetation index ; Zonal geography
. New concepts of tropical, annual tropical, true tropical and tropical fluctuating zone are formed to understand tropical area. Based on the indexes of climate, vegetation and soil, boundaries of tropical, annual tropical, true tropical and tropical
fluctuating zone of the study area are established. The tropical fluctuating zone explains different locating of different researchers. This paper also puts forward a new method to display boundary for eco-geographic regions.
The A. briefly reviews major themes in published tropical forest research between 1991 and 1992 inclusive in an attempt to identify what questions are believed to be important.
Biogeography ; Ecology ; Ecosystem ; Forest ; Habitat ; Photosynthesis ; Tree species ; Tropical rain forest
The A. reviews the mainstream ecological literature from 1994 to 1995 to gauge the importance of ecophysiological studies in understanding the ecology of tropical rain forests.
The A. reports on the progress in describing and explaining variation of biodiversity in tropical rain forests. He bases this review on a search of the 1997 editions of Ecology Abstracts, Ecological Abstracts and Forestry Abstracts.

China ; Climatic zone ; Flood ; Hydrology ; Pic discharge ; Precipitation ; Rainstorm ; Seasonal variation ; Spatial distribution ; Tropical cyclone
Regional distribution of the rainstorms and floods caused and affected by tropical cyclones are described and the geographical divisions of China are also given in this paper. The hydrological characteristics of tropical cyclone rainstorms
and floods are discussed and compared with that on non-tropical cyclones.

It is debatable whether tropical geomorphology is intrinsically different from the geomorphology of other places. This paper primarily examines the research themes of the last ten years or so, identifies the major trends, and attempts to predict
areas where interest is expected to concentrate in near future. The following topics among the current research trends are highlighted : geochemical erosion, movement on tropical slopes, rivers in the tropics, tropical landforms, hydrology
and sedimentation in the rainforest, denudation efficiency in the humid tropics, the Quaternary evolution and changes, and the applied side of tropical geomorphology.
An appreciation of time on a variety of scales may help explain the complexity of tropical rain forests and provide a frame of reference to consider the consequences of anthropogenic deforestation and global climatic change on this biome. Here
the A. reviews published tropical rain-forest research that has focused on the time dimension from late 1992 until early 1994.

The characteristics of a destructive tropical cyclone season in the South West Indian Ocean are analyzed. The areas of cyclogenesis and dissipation are examined. The development of Cyclone Demoina is tracked. - (AJC)

The Fremantle area provides safe shelter in the inner harbour or in Cockburn Sound from tropical cyclones. Large ships anchoring in Gage Roads would be more vulnerable to strong winds and seas associated with intense tropical cyclones. (JPB).

According to Hainan Island's biological characteristics, and existing structure of productivity of tropical crops and local climatic conditions, this paper carries on regional division of tropical crops by fuzzy mathematics. Based on calculation
of basic parameters for the formation of production, near-term optimum models of tropical crops structure of each region was established by means of multi-objective programming.
The seasonal variations of global wind field in the tropics mainly at 850 mb and their relation to the cloud distribution revealed from outgoing longwave radiation (OLR) are studied based on 5-day mean data. Seasonal composite maps of wind and OLR

Rainfall associated with tropical cyclones contibutes a significant amount to the annual rainfall in the southeastern United States. This study quantifies this amount from 1980-2004 and aims to determine the contribution of tropical cyclone-induced
