“…The iterative χ 2 technique used in this study was the same as that previously used to determine the association of daily weather occurences for apple produciton (Caprio and Quamme 1999) and for winter kill of wheat (Kalma et al 1992). A long set of annual production data from 1930 to 1989 (60 yr) for the Okanagan and Similkameen Valleys was available for this study (John Vielvoye, grape extension specialist, British Columbia Ministry of Food and Agriculture, now retired, Kelowna, BC) (Fig.1).…”

“…The associations between daily weather measurements and apple production for the Okanagan Valley of British Columbia (Caprio and Quamme 1999) and winter kill of wheat in Montana (Kalma et al 1992) were determined from long-term records using an iterative χ 2 method. In this study, the iterative χ 2 method was applied to historical records to ascertain the associations between weather and grape production (Vitis spp.…”

An iterative χ2 method applied to 60 yr of records in the Okanagan Valley of British Columbia (1930–1989) revealed that the main climatic factor limiting grape production (Vitis spp. and Vitis vinifera L.) was low temperatures (critical value range, ≤–6°C to ≤–23°C) occurring during late October, November, December and February. Daytime temperatures ≤–9°C during late November and early December benefited grape production, probably because it prevented vine de-acclimation. Detrimental effects of precipitation during late October were probably associated with the early movement of Arctic fronts into the region. Beneficial effects of precipitation in the form of snow were observed in January. During the pre-harvest growing season, except for a 2-wk period in July, high temperatures (≥26°C) were associated with good production, probably because warm temperatures are required for flower bud initiation and development. In contrast, higher-than-normal temperatures were not beneficial to production during the harvest year. Detrimental effects of high temperature were observed during July of the pre-harvest year and July (≥32°C) and early August of the harvest year (≥28°C). During the growing season, rainfall was sometimes unfavourable for grape production under irrigation, either because of associated cool weather or greater disease occurrence. Both temperature and precipitation were greater in the last 18 yr of the study than the prior 36 yr, especially during the late winter and early spring. The anticipated climatic change appears to favour grape production in the Okanagan Valley. Key words: grape, climate change, heat stress, winter injury

“…Other ways would be to avoid risky areas such as low-lying depressions and west-facing slopes when dealing with susceptible crops. Other management practices to avert losses would be to modify the physical environment of the crop following the methods suggested by Synder and De Melo-Abreu (2005), Kalma et al (1992) and Wratt et al (2006). These methods include wind induction, sprinkler irrigation, smoky fires on the farm, mulching and adoption of green house technologies.…”

“…They are influenced by terrain aspects combined with meteorological factors such as wind, clouds and humidity. Research by Kalma et al (1992) verified that cloud cover, wind and elevation, could be combined in an equation to give a good prediction of the expected minimum ground temperature at any particular site. In addition, Avissar and Mahrer (1988) developed a model that combines the factors that affect minimum night land surface temperature (LST) to include topography, humidity, land cover, soil moisture and wind velocity.…”

“…Long-term weather station temperature recordings have been used to produce frost risk maps of the Altiplano in Peru and in Israel as reported in Richards and Mandy (2003). Kalma et al (1992) used mobile temperature surveys and elevation models to evaluate the relationship between frost characteristics and geographic variables. Recently, Moderate Resolution Imaging Spectroradiometer (MODIS) remotely sensed data were used by Pouteau et al (2011) to estimate the probability of frost occurrence over the arid Andean Highlands of Bolivia.…”

Traditionally, methods used in the creation of composite temperature records have depended, implicitly or explicitly, on the assumption that the difference in temperature between two nearby sites will be a constant for any day in a given month of the year. It is demonstrated that this assumption is not necessarily valid, particularly where the sites used in the creation of a composite record differ in local topography. Two techniques are proposed to relate daily maximum and minimum temperatures at two sites during a period of overlapping records to overcome this difficulty. It is demonstrated using data from Inverell, Australia, where the difference in daily minimum temperature between two sites is significantly dependent on the temperature at one of the sites, that these techniques substantially improve the accuracy of the simulation of daily minima at one site using records from the other. The best choice of technique depends on whether the highest priority is to simulate the overall temperature record or the frequency and nature of extreme events.
