USDA Monthly World Weather Highlights

November 9, 2011 02:59 AM

As part of the monthly USDA S&D Report, USDA Joint Ag Weather Facility has issued the following weather highlights:

  • UNITED STATES: During October, mostly dry weather in the Mississippi Valley—including the western Corn Belt—allowed autumn fieldwork to near completion. In stark contrast, winter wheat planting and corn and soybean harvest activities trailed the normal pace in the eastern Corn Belt, due to late maturation of summer crops and autumn wetness. Wet conditions also extended into the Northeast, where a late-October snow storm highlighted the continuation of a soggy weather regime. Farther south, tropical showers soaked Florida’s peninsula, while drier-than-normal weather favored October fieldwork across the remainder of the lower Southeast. Meanwhile on the Plains, beneficial showers provided moisture for winter wheat emergence and establishment. Precipitation was particularly important on the drought-stricken southern Plains. Elsewhere, hit-ormiss showers accompanied mild weather in the West. The Western precipitation, beneficial from the standpoint of providing moisture for winter grains and
    establishing high-elevation snow packs, did not cause significant fieldwork disruptions.

  • SOUTH AMERICA: Seasonal rainfall increased throughout key production areas of Argentina, improving winter grain prospects and providing timely moisture for germination of summer grains, oilseeds, and cotton. In Brazil, the arrival of the rainy season spurred rapid planting of soybeans and other summer row crops and induced flowering of coffee.

  • EUROPE: Abnormally wet October weather over southeastern Europe hampered cotton harvesting in Greece but boosted soil moisture for winter grain establishment in the lower Balkans. In contrast, dry weather accelerated summer crop harvesting across Italy, Spain, and southern France but signaled a slow start to the rainy season on the Iberian Peninsula. Drier-than- normal conditions across Germany and Poland favored late summer crop harvesting. Despite season-ending freezes over most of central and northern Europe, winter crops were not yet dormant at month’s end.

  • FSU-WESTERN: In October, favorably wet weather across southern and central Russia favored winter grain establishment. In Ukraine, pockets of unfavorable dryness impeded winter crop establishment but favored corn and sunflower harvesting. Spring grain harvesting continued with minimal delay across Kazakhstan and Russia’s Siberia District, as the region remained devoid of snow cover until month’s end.

  • NORTHWESTERN AFRICA: Across much of northern Morocco, Algeria, and Tunisia, above-normal rainfall boosted topsoil moisture and encouraged early winter grain planting. Rain was locally excessive in eastern crop districts, causing flooding and hampering fieldwork.

  • MIDDLE EAST AND TURKEY: Wet October weather boosted soil moisture for winter grain planting and establishment over much of the region. However, locally heavy rain in western Turkey hampered cotton harvesting.

  • SOUTH ASIA: A resurgence of monsoon moisture into west-central India in early October gave way to seasonably drier weather. Reproductive cotton in Maharashtra and Andhra Pradesh was the main beneficiary of the late-season moisture. The continuation of seasonal rainfall in southern India benefited both late-season and winter (rabi) cotton and groundnuts. Warm, sunny weather favored winter wheat and rapeseed planting across northern states and into northern Pakistan.

  • EASTERN ASIA: Wet weather continued into early October across eastcentral China, hampering cotton and corn harvesting but improving moisture reserves for winter wheat planting. Winter rapeseed planting, underway through the month in the Yangtze Valley, benefited from unseasonably warm, sunny conditions. Meanwhile, persistent heavy rainfall in Sichuan slowed rapeseed planting but boosted irrigation supplies. In the northeast, harvesting of corn, rice, and soybeans neared completion by month’s end, facilitated by cool, dry weather.

  • SOUTHEAST ASIA: Flooding continued into October across central Thailand, spurred by record rainfall for the season. The flooding reduced wet-season rice prospects. By early November, easterly winds ushered in the dry season to Thailand, aiding flood recovery and rice replanting efforts. However, the turn to easterly winds brought flooding rains to the eastern Philippines, where replanting of winter rice was necessary.

  • AUSTRALIA: In October, above-normal rainfall in Western Australia benefited immature winter grains and oilseeds but hampered dry down and harvesting of mature crops. Similarly, wet weather in northern New South Wales and southern Queensland slowed fieldwork, including winter wheat harvesting, but aided early cotton and sorghum development. In southeastern Australia, intermittent showers favored filling winter crops while periods of warm, dry weather helped wheat, barley, and canola maturation and harvesting.

  • SOUTH AFRICA: In October and early November, showers improved conditions for summer crop planting in eastern sections of the corn belt. Moisture remained limited, however, for rain-fed sugarcane.
