Climatological characteristics of the tropics in China: climate classification schemes between German scientists and Huang Bingwei

Reviewing some important German scientists who have developed climatic regionalization schemes either on a global or Chinese scale, their various definitions of the tropical climate characteristics in China are discussed and compared with Huang Bingwei's climate classification scheme and the identification of the tropical climate therein. It can be seen that, due to different methodological approaches of the climatic regionalization schemes, the definitions of the tropics vary and hence also their spatial distribution in China. However, it is found that the tropical climate type occupies only a peripheral part of southern China, though it firmly represents a distinctive type of climate that is supsequently associated with a great economic importance for China. As such, the tropical climate type was mostly identified with its agro-climatological significance, that is by giving favourable growing conditions all-year round for perennial crops with a great heat demand. Tropical climate is, hence, conventionally regarded to be governed by all-year round summer conditions "where winter never comes".

The tropical forest in south east Asia: Monitoring and scenario modeling using synthetic aperture radar data

Tropical forests play a major role in storing large carbon stocks and regulating energy, and water fluxes, but such forest cover is decreasing rapidly in spite of the policy attention on reducing deforestation. High-resolution spatiotemporal maps are unavailable for the forests in majority of the tropical regions in Asia because of the persistent cloud cover and haze cover. Recent advances in radar remote sensing have provided weather-independent data of earth surface, thus offering an opportunity to monitor tropical forest change processes with relatively high spatiotemporal resolutions. In this research, we aim to examine the tropical deforestation process and develop a spatial model to simulate future forest patterns under various scenarios. Riau Province from central Sumatra of Indonesia is selected as the study area; this province has received much attention worldwide because the highest CO₂ emission resulting from tropical deforestation has been recorded. Annual time series PALSAR data from 2007 to 2010 were analyzed for forest mapping and detecting land cover changes. A spatial model was calibrated using the Bayesian method. Modeling parameters were customized for the local subregions that allocate deforestation on the basis of their empirical relationships to physical and socioeconomic drivers. The model generated landscape spatial patterns mirrored the possible locations and extent of deforested areas by 2030 and provided time-series crucial information on forest landscape under various scenarios for future landscape management projects. The results suggested that the current deforestation process is in a critical stage where some subregions may face unprecedented stress on primary forest costing rivers and forest ecosystems by the end of 2020. The perspective views of Riau Province generated by the model highlighted the need for forest/environmental planning controls for the conservation of environmentally sensitive areas.

西北太平洋热带气旋快速增强与环境垂直风切变统计分析

利用1990-2009年美国联合台风警报中心整编的热带气旋（TC）最佳路径资料和NCEP/NCAR再分析等压面流场资料,在分析西北太平洋TC每24 h强度变化统计特征的基础上,确定了西北太平洋TC快速增强的阈值,对比不同阈值条件下,TC快速增强初始时刻的强度,TC快速增强发生的季节变化和空间分布特征,进一步研究环境垂直风切变与TC快速增强的关系。结果表明：在西北太平洋海区,当TC强度24 h变化达到样本累积百分率的88%、90%、93%和96%的概率时,对应的强度变化值分别为25 KT、30 KT、35 KT和40 KT,定义它们为TC快速增强的阈值。该阈值越大,快速增强初始时刻的强度也越强。60%左右的TC快速增强发生在8-10月,TC快速增强的空间分布集中于125°-150°E、10°-25°N的矩形区域内。对流层不同层次的垂直风切变与TC快速增强的关系有差异,TC快速增强阈值为40 KT时对应的对流层中上层（200~500 hPa）、对流层中下层（500~850 hPa）和对流层（200~850 hPa）的垂直风切变值的概率分布显示：当垂直风切变≥12 m/s时,分别只有9.7%、1.5%、11.1%的TC可以快速增强;且其与TC快速增强时强度变化的相关系数分别为-0.15、0、-0.04,以200~500 hPa的最为显著,表明对流层中上层垂直风切变对TC强度增强的抑制作用最明显。在TC快速增强阈值为40 KT的初始时刻,将200~850 hPa垂直风切变划分为东风切变和西风切变的统计表明,57%的TC在东风切变的环境下可以快速增强。
