Soil freeze thaw
WebJan 31, 2011 · Latent heat flux displayed distinctly better correlation with unfrozen soil water content during the freezing and thawing stages than during the completely frozen and thawed stages. This implies that the diurnal cycle of unfrozen soil water, resulting from diurnal freeze/thaw cycles at the surface, has a significant impact on latent heat flux. WebApr 13, 2024 · Deep soil frost may not be only culprit for frozen pipes. A frozen PVC water pipe dug out for thawing. Water lines in the Seeley Lake area have been freezing solid quite late this year, but it's not so much from a change in weather as it is from a change in the town's population.
