摘要:

對(duì)FY-3A氣象衛(wèi)星大氣溫度濕度廓線資料進(jìn)行夜間大霧低能見(jiàn)度分布反演計(jì)算，并運(yùn)用美國(guó)LAPS（Local Analysis and Prediction System）局地分析與預(yù)報(bào)系統(tǒng)，與FNL再分析資料多要素反演數(shù)據(jù)進(jìn)行多源要素融合分析。FY-3A衛(wèi)星反演得到的大霧低能見(jiàn)度分布，經(jīng)與Micaps（Meteorological Information Comprehensive Analysis and Process System）系統(tǒng)地面天氣圖，F(xiàn)Y-2E地球同步衛(wèi)星紅外云圖，要素統(tǒng)計(jì)氣象年鑒記錄等對(duì)比檢驗(yàn)，顯示反演的低能見(jiàn)度區(qū)范圍及強(qiáng)度合理。尤其是對(duì)海上缺乏常規(guī)觀測(cè)資料網(wǎng)的海域，提供了夜間海上能見(jiàn)度分布信息。進(jìn)一步地通過(guò)LAPS系統(tǒng)對(duì)比衛(wèi)星資料、再分析資料、以及衛(wèi)星與再分析資料融合的3種方案結(jié)果，顯示將衛(wèi)星監(jiān)測(cè)資料與FNL再分析資料的融合效果，對(duì)單來(lái)源資料反演的大霧低能見(jiàn)度分布有較好的改善。融合后對(duì)衛(wèi)星資料而言，衛(wèi)星軌道盲區(qū)已經(jīng)彌合，其次，獲得了海上低能見(jiàn)度區(qū)分布的信息，對(duì)海上和沿海霧區(qū)能見(jiàn)度的強(qiáng)度得到合理改善。對(duì)于FNL再分析資料，原有的各項(xiàng)要素強(qiáng)梯度被合理平滑。低能見(jiàn)度范圍也有調(diào)整改善。重要的是海上大霧低能見(jiàn)度區(qū)的分布，得到FY-3A衛(wèi)星信息和數(shù)值模擬信息的互相驗(yàn)證與信息綜合，可信度增強(qiáng)。

Abstract:

The inversion calculation of the atmospheric visibility data of the FY-3A meteorological satellite was performed in this paper. The LAPS (Local Analysis and Prediction System) of the United States was used to calculate the inversion of the visibility data of the night fog and the multi-element inversion of the FNL reanalysis data. Data was analyzed by multi-source feature fusion. The low-visibility distribution of fog resulting from the inversion of FY-3A satellite was compared with the weather map of the Micaps (Meteorological Information Comprehensive Analysis and Process System) system, the infrared cloud map of the FY-2E geosynchronous satellite, and the statistical yearbook of the elemental statistics, showing that the range and intensity of the invisible low visibility area were reasonable. In particular, the absence of conventional observational data networks in the sea areas provided information on the distribution of visibility at night. Through the LAPS system comparison of satellite data, reanalysis data, and satellite and reanalysis data fusion results, the fusion effect of the satellite monitoring data and the FNL reanalysis data was shown, bringing a better improvement on the fog low visibility distribution retrieved from single-source data. After the fusion, the satellite orbital blind area had been bridged for satellite data. Secondly, information on the distribution of low-visibility areas at sea had been obtained, and the visibility of the sea and coastal fog areas had been reasonably improved. For FNL reanalysis data, the strong gradients of the original elements were reasonably smoothed. The scope of low visibility had also been improved. The distribution of low-visibility areas in the sea fog was vital, and the mutual verification and information integration of numerical simulations and FY-3A satellite information were obtained and the credibility was enhanced. Therefore, LAPS data fusion effect is worthy of recognition, and it has good reference value for forecasting and early warning.
