To mitigate spring frost damage, fruit farmers use wind machines to mix warm overlying air down the vegetation. Up this point, studies on machine efficiency have focused temperatures. The temperature of different plant organs during operation remains unknown, while critical for actual degree damage. With Distributed Temperature Sensing we measured vertical in-canopy profiles in a pear orchard N...

Frost damage to the flowers and early developing fruits is one of the most limiting factors in almond cultivation regions of the world. This study was undertaken to understand almond response to frost damage concerning ion leakage in order to develop a criterion for the selection of frost-resistant cultivars in field experiments. In this work, 60 almond cultivars and genotypes on the basis fros...

Frost heave, which is the volumetric expansion of frozen soil, has great ecological significance, since it creates water storage spaces in soils at the beginning of the growing season in cold temperate forests. To understand the characteristics of frost heave in seasonally frozen soil and the factors that impact its extent, we investigated the frost heave rates of forest soil from different dep...

We used field observations of frost-boil distribution, soils, and vegetation to attempt to validate the predictions of a Differential Frost Heave (DFH) model along the temperature gradient in northern Alaska. The model successfully predicts order of magnitude heave and spacing of frost boils, and can account for the circular motion of soils within frost boils. Modification of the model is neede...
