Polar Air Outbreaks in the Americas Assessments and Impacts During Modern and Past Climates

Polar outbreaks have long attracted the attention of meteorologists and climatologists. They are described here in terms of their air temperatures, air mass central pressures, and wind characteristics, as well as in relation to the atmospheric circulation and their trajectories over the continents. Outbreaks of polar air into low latitudes tend to organize tropical convection and rain in summer, while the cold air tends to produce cooling in lower latitudes and freezes in the subtropics during winter. Cold waves accompanying polar outbreaks have other significant impacts in the Americas, including adverse effects on coffee production in South America and on citrus production in North America. Synoptic events leading to cold waves are somewhat similar in the Americas, particularly in terms of the upper air patterns and forcing, but the intensity of the outbreaks in terms of temperature and pressure is larger in North America. Typically, they are associated with an amplified ridge lying...

Examples of phytochemical extracts from plant food wastes

Extracts containing large amounts of citrus flavanones are obtained from the wastes of the citrus-juice industries (Braddock, 1995). Different fla-vanone profiles can be obtained depending on the citrus species. Sweet oranges produce extracts in which hesperidin is the main constituent, while neohesperidin is the most characteristic of sour oranges, naringin of grapefruits and eriocitrin of lemons. Many applications for these extracts have been reported, both for their biological activity and for their potential uses as food antioxidants.

Utilization of microclimates in agriculture

Citrus growers in California or Florida sometimes resort to putting radiant heaters in the open air of the orchards if a frost is threatening it is a very inefficient use of fossil fuel energy, but often works just well enough to keep frost off the plants. In another trick to keep frost off, rice farmers in northern Japan often raise the water level in their rice fields to flood the plants with a layer of insulating water to protect them against a sudden cold spell, during the most sensitive period when the rice is flowering and the grains are beginning to form.

Important sources of highvalue coproducts 1751 Fruit processing

The use of citrus by-products is a traditional industry and was reviewed 10 years ago by Braddock (1995). Essential oils are directly produced in the juice production plants as a co-product and have a market. The main wastes include the citrus peels and residues from segments and seeds after pressing. These residues are rich in pectins, and flavonoids (flavanones) and limonoids are present in minor amounts. Flavanones are generally extracted in alkaline water, the extracts are then acidified and the flavanones, which are slightly soluble in water, precipitate. There are differences in the flavo-noid content of different citrus species and this can be used for production of specific extracts enriched in compounds with specific properties. Thus, grapefruit is rich in bitter naringin that can be further chemically transformed into the intensely sweet dihydrochalcones. Lemon is rich in eriocitrin, a flavanone with higher in vitro antioxidant activity than flavanones from other citrus...

Sourcesink relations and fruit production

Climatic variables, have been intensively studied (Wibbe et al., 1993 Buwalda and Lenz, 1995). Among all tree crops, cultivated fruit trees are the ones most adequately supplied with water and nutrients thus, there should be few, if any, constraints to a positive CO2 response. However, very few studies have dealt with the effects of increased CO2 concentrations on fruit production (Goodfellow et al., 1997). The best known study is that of Idso's group, who grew eight citrus trees in open-top chambers for 7 years (Idso and Kimball, 1997). Results showed that under elevated CO2 there was an increase in growth of the vegetative tree parts and that while the number of fruits increased, their size did not.

Cross Sectional Analysis

The hedonic analysis has been extensively applied in World Bank studies using both farmland values as well as net revenue (a profit measure) as the dependent variable. Since farmland values are the discounted sum of all future net benefits that can be obtained from a piece of land if it is put to the best use, the two are closely related. It should, however, be noted that the cross-sectional analysis is linking farmland values or average profit measures to average weather variables. It is questionable to link profit in one particular year to average weather variables, as random weather outcomes would induce considerable noise and could severely bias the analysis. Citrus trees in California and Florida are usually highly profitable. Yet, in a year when there is a late freeze that kills the harvest and results in very low profits, linking profits from that particularly year to average weather outcomes where freezes only occur infrequently could be very misleading. The next section about...
