GENEVA -- Each year, the World Health Organization (WHO) Global Influenza Programme convenes meetings to analyse the global data on circulating influenza virus strains and make recommendations for the vaccine to be used for the coming influenza season. This year's analysis, which concluded yesterday, was conducted by members of the WHO Collaborating Centres on Influenza and has recommended that vaccines to be used in the 2005-2006 season (Northern Hemisphere) should contain the following: http://www.who.int/mediacentre/news/notes/2005/np05/en   (419 words)      The Seasons Thus, we experience Summer in the Northern Hemisphere when the Earth is on that part of its orbit where the N. Hemisphere is oriented more toward the Sun and therefore the Sun rises higher in the sky and is above the horizon longer, and the rays of the Sun strike the ground more directly. There is a popular misconception that the seasons on the Earth are caused by varying distances of the Earth from the Sun on its elliptical orbit. The primary cause of the seasons is the 23.5 degree of the Earth's rotation axis with respect to the plane of the ecliptic, as illustrated in the adjacent image (Source). http://csep10.phys.utk.edu/astr161/lect/time/seasons.html   (964 words)      RealClimate » Moberg et al: Highly variable Northern Hemisphere temperatures?

These points will undoubtedly be answered, and the authors of other temperature reconstructions (including other authors at RealClimate) will have comments on the method. This result will undoubtedly lead to much discussion and further debate over the validity of previous work. http://www.realclimate.org/index.php?p=122   (8192 words)      JPL.NASA.GOV: News Releases The ring shadows at higher latitudes correspond to locations on the ring plane that are farther from the planet - in other words, the northernmost ring shadow in this view is cast by the outer edge of Saturn's A ring. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

The Earth is closest to the Sun in late December, but this is definitely not the warmest time of the year for people living in the northern hemisphere! It is also the day that the Sun reaches its highest point in the sky. http://teacher.scholastic.com/researchtools/articlearchives/space/solstice.htm   (675 words)      Southern Hemisphere - Wikipedia, the free encyclopedia This generally causes sun-cast shadows to turn anticlockwise through the day. This page was last modified 09:35, 3 February 2006. This is because the Southern Hemisphere has significantly less land and more ocean, and water heats up and cools down more slowly than land. http://en.wikipedia.org/wiki/Southern_hemisphere   (381 words)      Consequences of Rotation for Weather This fact means that projectiles moving across the Earth's surface are subject to Coriolis forces that cause apparent deflection of the motion. This is a consequence of the Coriolis force, as illustrated for the Northern hemisphere in the following figure. The Coriolis force deflects to the right in the Northern hemisphere and to the left in the Southern hemisphere when viewed along the line of motion. http://csep10.phys.utk.edu/astr161/lect/earth/coriolis.html   (680 words)      [No title] This is a relatively brief timespan considering the slowness of changes in background conditions, and the dramatic nature of the shift in the Earth's surface conditions that was involved. This theory is supported by some computer simulations of the ice-and-climate system; these suggest that it is possible to build up Northern Hemisphere ice sheets over a relatively brief 200,000 years, at around 2.75 to 2.55 Ma, by varying only the seasonal solar radiation pattern controlled by the orbital parameters (Maslin et al. The onset of Northern Hemisphere glaciation - when large ice sheets first spread over the northern continents - culminated in the intense glacial-interglacial cycles that define the Quaternary, and began a unique period in Earth history in which both poles (rather than just one of them) have remained ice locked. http://www.esd.ornl.gov/projects/qen/onset.html   (609 words)      The Straight Dope: Do bathtubs drain counterclockwise in the Northern Hemisphere? The supposed reason for this "fact" is the Coriolis effect, which has to do with the effect of the earth's rotation on moving objects. All this was demonstrated way back in 1962 by one Ascher Shapiro, a researcher at the Massachusetts Institute of Technology. The boring truth is that water drains every which way no matter what hemisphere you're in, for reasons which have to do mostly with the shape of the drain, the way you poured in the water in the first place, and so on. http://www.straightdope.com/classics/a1_161   (594 words)      EO News: Satellite Data Help Researchers Track Carbon in Northern Hemisphere Forests - December 11, 2001 Right now, scientists have inferred that there is a sink of 1 to 2 billion tons of carbon into the land regions of the northern hemisphere, which corresponds to some 15 to 30 percent of the global annual industrial carbon emissions. NASA-funded Earth Science researchers, using high-resolution maps of carbon storage derived from NASA-developed satellite data sets, suggest that forests in the United States, Europe and Russia have been storing nearly 700 million metric tons of carbon a year during the 1980s and 1990s. The researchers suggest a longer growing season from climate- warming in the north, fire suppression and forest re-growth in the United States, better forest management in the Nordic countries and declining harvests in Russia as possible reasons why some forests are storing carbon. http://earthobservatory.nasa.gov/Newsroom/NasaNews/2001/200112116306.html   (868 words)      Most of earth's land is in the Northern Hemisphere Since most of the land is in the Northern Hemisphere, it's natural that the people who invented mechanical clocks would live in the Northern Hemisphere and would make the hands on their clocks mimic the direction a shadow moves on a sundial. "Clockwise" is the direction shadows move in the Northern Hemisphere. I have no explanation for why this is, but it probably explains why most maps of the world are oriented with the North side up. http://home1.gte.net/deleyd/religion/solarmyth/nh.html   (400 words)      Northern Hemisphere - Simple English Wikipedia Northern Hemisphere: North America and the top part of South America (left); Eurasia and the top of Africa (right) The Northern Hemisphere is the part of the Earth that is north of the equator. This short article needs someone to make it better. http://simple.wikipedia.org/wiki/Northern_Hemisphere   (87 words)      35 Fun Facts Earth’s axis is tilted in relation to the Sun. This is because when the North Pole is tilted towards the Sun, the South Pole is tilted away from it, and vice versa. As Earth continues its orbit, the North Pole begins to tilt away from the Sun, and the Northern Hemisphere receives a decreasing amount of daylight. http://www.letoy.co.uk/35_fun_facts.htm   (481 words)      Winter Solstice The reason for the different seasons at opposite times of the year in the two hemispheres is that while the earth rotates about the sun, it also spins on its axis, which is tilted some 23.5 degrees towards the plane of its rotation. As the Earth continues its orbit the hemisphere that is angled closest to the sun changes and the seasons are reversed. In the Northern Hemisphere, the winter solstice occurs either December 21 or 22, when the sun shines directly over the tropic of Capricorn; the summer solstice occurs either June 21 or 22, when the sun shines directly over the tropic of Cancer. http://www.infoplease.com/spot/wintersolstice1.html   (319 words)      Tropical Waters in Northern Hemisphere Heating at an Accelerated Rate, NOAA Reports TROPICAL WATERS IN NORTHERN HEMISPHERE HEATING AT AN Tropical waters in the Northern Hemisphere have been heating at an enhanced rate since 1984, NOAA scientists reported today. Analyses of the Atlantic, Pacific, and Indian Oceans, when taken as a whole, indicate that from 1984 to 1996, a rather robust warming has been taking place over the Northern Hemisphere tropics, close to what has been referred to as the thermal equator, Strong said.

"The Northern Hemisphere surface temperature has shown a warming trend over the past several decades to values that are perhaps unprecedented over the past 1,000 years," write the authors, and the NAO change has been a key player in this. Through the 1980s and 1990s, the NAO entered and maintained a largely "positive" phase characterized by stronger-than-average westerly winds across the middle latitudes of the Atlantic Ocean and into Europe, southerly flow over the eastern United States, and northerly flow across western Greenland, the Canadian Arctic, and the Mediterranean. http://www.sciencedaily.com/releases/2001/04/010406073554.htm   (996 words)      EO News: Greenhouse Gases Cause Northern Winter Warming - April 23, 2001 Greenhouse gases are the main reason why the northern hemisphere is warming quicker during winter-time months than the rest of the world, according to new computer climate model results by NASA scientists. NASA scientists input all of these factors in a climate model and concluded that greenhouse gases are the primary factor driving warmer winter climates in North America, Europe and Asia over the last 30 years. The findings by Drew Shindell, Gavin Schmidt, and other atmospheric scientists from NASA’s Goddard Institute for Space Studies and Columbia University, NY, appeared in the April 16 issue of the Journal of Geophysical Research - Atmospheres. http://earthobservatory.nasa.gov/Newsroom/NasaNews/2001/200104234686.html   (686 words)      Northern Hemisphere circumpolar vortex trends and climate change implications Trends in the Northern Hemisphere circumpolar vortex at 700, 500, and 300 hPa are examined to assess the relationship between circulation variability and air temperature. Spatial examination of the vortex indicates that the pre-1970 expansion and post-1970 contraction were driven primarily by expansion/contraction over Asia, Europe, and North America with little change over the Northern Hemisphere oceans. Although significant climate change debate focuses on the discrepancy between positive trends in surface air temperature and little or no trends in Microwave Sounding Unit (MSU) satellite temperatures, contraction of the circumpolar vortex at every level of the atmosphere implies that the atmosphere is warming at depth since 1970. http://www.agu.org/pubs/crossref/2003/2002JD002958.shtml   (466 words)      SOTC: Snow Image courtesy of R.L. Armstrong and M.J. Brodzik, National Snow and Ice Data Center, University of Colorado, Boulder (Armstrong and Brodzik, 2001). Because snow has such a high albedo compared to other surfaces on Earth, snow-covered areas appear much brighter in satellite imagery than most other surface types. The time series of differences between the snow-covered area for each month in a given year and the long term average for that month (departure from the mean) indicate similar trends in the two data sets. http://nsidc.org/sotc/snow_extent.html   (850 words)      SOTC: Permafrost If the high northern latitudes were to have a significant temperature increase, the regional soils would begin to release carbon into the atmosphere, which could lead to increased plant growth, carbon aspiration, and possibly a temperature drop or stabilization.
