The evolution of atmospheric factors and sea ice growth of the Arctic high latitude region process are analyzed based on the data observed by the drifting automatic weather station over the period from August 2018 to May 2019. The evolution shows two different phases according to the sea ice drifting trajectory. The sea ice mainly drifted to the southeast in the first phase and drifted to the northeast in the second phase. The averaged air temperature and averaged relative humidity are −6.6℃ and 93% for the first phase and those are −29.3℃ and 76% for the second phase. The averaged pressure is higher in the second than that in the first phase. The sea ice drifting trajectory are mainly affected by the Beaufort High. The sea ice velocity from automatic weather station derived and NSIDC (National Snow and Ice Data Center) are compared and the result show that the zonal velocity is unanimous. The sea ice is mainly melting in the first and sea ice thickness show decrease in the first phase. The sea ice growth rate is −0.11 cm/d in August. The sea ice growth mainly occurs in the second phase. The sea ice growth rate is larger than 0.9 cm/d from January to March 2019. The largest monthly averaged sea ice growth rate is in March with the value of 1.1 cm/d and the sea ice keep growth until the end of the observation period.
