Loss of body heat from young animals soon after birth is asignificant cause of lamb mortality on New Zealand farms eachspring. Key drivers of heat loss are the ambient air temperature,wind, which increases convective heat loss, and skin wetness,which causes evaporative heat loss.
Weather models can provide estimates of wind chill risk on different time scales, and provide some warning of high risk periods.
