Climate Report over Japan
Monthly Highlights
- In eastern/western Japan and Okinawa/Amami, monthly mean temperatures were above normal with the highest on record for February since 1946 in Okinawa/Amami, since warm airs covered over the regions in the most of the month. In northern Japan, monthly mean temperatures were above normal due to significantly warm air in late February, although temperatures were remarkably low in the first half of the month.
- Monthly snowfall amounts for the Sea of Japan side were significantly below normal due to small effect of cold air and developed low pressures.
