資料來源與使用狀況(Data & Sources)

為確保視覺化內容的學術準確性,本頁面整理了參考數據的來源及視覺化中的使用狀況。

1. 數據集(參考來源)

季風(地表10m)
ERA5 reanalysis (10m wind, 2000-2020 climatology, 0.25° resolution)
CDS: https://cds.climate.copernicus.eu/datasets/reanalysis-era5-single-levels-monthly-means
噴射氣流(250hPa)
ERA5 reanalysis (250hPa wind, 2000-2020 climatology, 0.25° resolution)
CDS: https://cds.climate.copernicus.eu/datasets/reanalysis-era5-pressure-levels-monthly-means
洋流(OSCAR)
OSCAR satellite-derived ocean currents (15m depth, 2019-2023 climatology, 0.25° resolution)
NOAA ERDDAP: https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplOscar.html

2. 使用範圍與期間

時間週期
monthly / 12 期間
標籤: 1月, 2月, 3月, 4月, 5月, 6月, 7月, 8月, 9月, 10月, 11月, 12月
邊界框
經度 75 – 290,緯度 -40 – 75

3. 解析度與網格

統一網格(所有圖層共用)
0.25° / 861 × 461
從v7.1起,季風、噴射氣流、洋流全部統一使用0.25°解析度,提升準確性。

4. 處理與表現(摘要)

- 月別氣候值經彙總後,內插至顯示網格進行視覺化。
- 洋流的OSCAR缺失值(NaN)模式作為海洋遮罩使用,以排除陸地區域。
- 儲存格式:int16 / scale=0.01 / compressed=true
- 強度表現:箭頭的長度、粗細、顏色濃度以6個等級顯示。

季風(地表10m)・噴射氣流(250hPa):ERA5

由 Create GBM 以哥白尼氣候變遷服務(C3S)的 ERA5 月平均資料(2000–2020年;地表10m風與250hPa風的東西、南北分量)計算各月的氣候平均值,並內插至顯示用的 0.25° 網格製作而成。
