Due to the freezing conditions, no crops were growing in the northeast of China during this monitoring season. CropWatch Agroclimatic Indicators (CWAIs) showed that the overall precipitation increased by 28%, and it was significantly above the 15YA in mid-November, late-December and mid-January. The photosynthetically active radiation decreased by 3%, and the temperature increased by about 0.3°C.  

In general, the above-average precipitation in the current monitoring season can be expected to have a positive impact on spring sowing. Adequate soil moisture, together with normal temperature and radiation will benefit the emergence and early growth of crops in the spring.
