Needle ice observations from the high Drakensberg, Lesotho
Abstract Near‐surface ground thermal conditions are a delayed response to changing air temperature and may result in needle ice development when air temperatures are above 0 °C and ground temperatures below 0 °C. It is difficult, therefore, to predict needle ice development based only on climatologi...
