Short summary

The East Asian winter monsoon causes orographic snowfall over the windward side of the Japanese islands (facing the Sea of Japan and the northwesterly winter monsoon flow) and negative temperature anomalies around Japan. In this study, we reconstruct the outbreak of the winter monsoon around Japan for the winter from the 1840s to the early 1850s by using daily weather information recorded in old Japanese diaries and early daily instrumental temperature data.
