摘要

了解大气特性和模式对马来西亚的国家航空航天蓝图、国家空间和立法至关重要。虽然已经颁布并实施了各种政策,但仍缺乏有关风廓线的信息,特别是马来西亚半岛高空的风廓线。考虑到有必要制定一个标准指南,供国家参考、未来研究、空间-航空航天应用和立法使用,本研究首次对马来西亚半岛的高层空气进行了风廓线分析。从马来西亚气象局收集了相关数据进行分析和评估。具体而言,在 7 年内(从 2015 年到 2021 年),每月 15 日 0000UTC (0800 h LT) 和 1200UTC (2000 h LT) 在吉隆坡国际机场和关丹气象站使用附有探测无线电探空仪的气象气球记录数据,以进行风廓线分析。一旦气球的上升率从垂直气流(卡塔巴赫风或消旋风)中稳定下来,就会准确记录每天的总体数据收集情况。随后,对收集到的数据进行评估,包括每年和每段时间的最小、最大和平均风速。最后,将各年、各时段的平均风速合并,生成马来西亚半岛风廓线。根据结果,两个站点的预测风廓线确定了马来西亚半岛低速风廓线的三个离散正弦波流类型的峰值。这三个峰值放大了最高气流速度,其中第 1 和第 2 个峰值分别位于海拔 9,000 米至 12,000 米的对流层(平均风速为 10.8 毫秒-1)和海拔 12,000 米至 18,000 米的对流层(平均风速为 13.7 毫秒-1)。第 3 个峰值位于海拔 18,000 米至 32,000 米的平流层(平均风速为 15.2 毫秒-1)。由于东马来西亚位于同一条赤道线上,因此风廓线假定是相同的,只有细微差别。总之,本研究中确定的马来西亚半岛高空风廓线将有助于今后的其他研究,并有助于马来西亚空域立法的长期规划。

Wind Profiles in Peninsular Malaysia: A Comprehensive Upper Air Analysis
Understanding the atmospheric properties and patterns is crucial in empowering Malaysia's national aerospace blueprint, national space, and legislation. While various policies have been enacted and implemented, there is a lack of information on the wind profile, specifically the upper air across Peninsular Malaysia. Realising the need to establish a standard guideline for national reference, future research, space-aerospace application, and legislation, this study was performed to develop the first wind profile analysis of upper air in Peninsular Malaysia. Relevant data from the Malaysian Meteorology Department was collected for analysis and evaluation. Specifically, a meteorology balloon attached with a sounding radiosonde was used to record data at 0000UTC (0800 h LT) and 1200UTC (2000 h LT) on the 15th day of each month for 7 years (from 2015 to 2021) at the KLIA and Kuantan Meteorology Stations for the wind profiling analysis. The daily overall data collection was recorded accurately once the balloon's rising rate stabilises from vertical air current (katabatic or anabatic winds). Subsequently, the collected data were evaluated in terms of the minimum, maximum, and average wind speeds for each year and time. Finally, the average wind speed of each year and time were combined to generate the Peninsular Malaysia wind profile. Based on the results, the projected wind profile for both stations identified three peaks of discrete sine wave flow type with low-speed wind profile in Peninsular Malaysia. The three peaks amplified the highest air velocity, whereby the 1st and 2nd peaks were located at the troposphere layer from 9,000 m to 12,000 m altitude (average wind speed of 10.8 ms-1) and 12,000 m to 18,000 m altitude (average wind speed of 13.7 ms-1). The 3rd peak was located at the stratosphere layer from 18,000 m to 32,000 m altitude (average wind speed of 15.2 ms-1). Since East Malaysia is located on the same equatorial line, the wind profile is hypothetically the same and exhibits only slight differences. In short, the established wind profile of upper air in Peninsular Malaysia in this study would facilitate other future studies and assist long-term planning of Malaysia's airspace legislation.
