Analysis of Frost Probabilities in Aydın, Türkiye

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2022
Frost events are of particular importance for plants. Its occurrence determines growing season. Early or late frost events may cause injuries and damage in plants which have not yet entered dormancy in fall/winter, and for plants in flowering period in ...

Experimental Study of Frost Crystals Dendrite Growth on Two Neighboring Separate Frozen Water Drops on a Cryogenic Cold Surface under Natural Convection Conditions

open access: yesEnergies, 2023
The effects of cold surface temperature, wet air state (temperature and humidity) and original drop size on frost dendrites growth of two neighboring separate frozen water drops of same size under natural convection conditions were investigated by ...

Experimental study on the evolution characteristics of cyclic frost heaving pressure of saturated fractured granite

open access: yesRock and Soil Mechanics, 2021
The frost heaving pressure generated by water–ice phase change and volume expansion of saturated fractured rock mass in cold regions promote the initiation and expansion of new fractures, and lead to further damage and deterioration of fractured rock ...

A review of crop frost damage models and their potential application to cover crops

open access: yesItalian Journal of Agronomy, 2022
Cover crops provide agro-ecological services like erosion control, improvement of soil quality, reduction of nitrate leaching and weed control. Before planting the subsequent cash crop, cover crops need to be terminated with herbicides, mechanically or ...

Effects of Temperature and Pressure on Frost Heaving

open access: yesEngineering Geology, 1979
Abstract Concerning the influence of overburden pressure on the relation between rate of heave and cold-side temperature, studies show that the heave rate for various overburden pressures tends to converge as the cold-side temperature is lowered, and the maximum rates of ice accumulation at low pressures occur at temperatures closer to 0°C than do ...

Evolution Patterns of Frost-Heaving Pressure with Partial Ponding in Cold Region Tunnels

open access: yesGeofluids, 2022
The calculation of the frost-heaving pressure is one of the key issues in the frost-resistant design of tunnels in cold regions. To reveal the frost heave mechanism of partial ponding behind the tunnel linings, a three-dimensional geo-mechanical model ...

Exogenous application of molybdenum affects the expression of CBF14 and the development of frost tolerance in wheat. [PDF]

open access: yes, 2013
Wheat is able to cold acclimate in response to low temperatures and thereby increase its frost tolerance and the extent of this acclimation is greater in winter genotypes compared to spring genotypes.

Spring frost risk in a changing climate

open access: yesGeophysical Research Letters, 2008
While both the mean and variance of daily temperature are forecasted to increase in future climate scenarios, studies of spring frost risk to vegetation have relied on changes in mean temperature to understand frost risk in these scenarios.

Experimental Research on Frost Indexes for Lycium Barbarum Flowering Phase

open access: yes应用气象学报, 2020
Based on researches of frost indexes of Lycium barbarum during 2016-2018, tests of frost index are performed using an artificial frost box in 2019, focusing on flower bud, early flowering and full flowering periods. The temperature of treatment is -8—-1℃,
