Although weatherforecasts have become more reliable, there is still a need for greater accuracy. Better forecasts could save industries across the world many billions of dollars each year. Farmers and engineers, in particular, would benefit. When I say this is stylish, I’m not kidding. There are four circular screens with golden edges set into a dark coloured casing. The overall effect is really eye-catching, albeit in a not too over the top way.

If meteorologists knew more about how the atmosphere functions, they would be able to make more accurateforecasts from day to day or even from week to week. Making such forecasts, however, would require knowing the temperature, atmospheric pressure, wind speed and direction, humidity, precipitation, and cloudiness at every point on the Earth. Doppler radar has made air travel safer. It lets air traffic controllers detect severe local conditions, such as microbursts. Microbursts are powerful winds that originate in thunderstorms. They are among the most dangerous weather phenomena a pilot can encounter. If an aircraft attempts to land or take off through a microburst, the suddenly changing wind conditions can cause the craft to lose lift and crash. In the United States alone, airline crashes because of microbursts have caused more than 600 deaths since 1964. Atmospheric pressure is the weight of the atmosphere overhead. Changes in atmospheric pressure signal shifts in the weather. A high-pressure system usually brings cool temperatures and clear skies. A low-pressure system can bring warmer weather, storms, and rain.

By early afternoon, the ice coring team had returned to camp, having drilled a 10-meter section of ice.

Matthews and Perry had come to Everest as part of an ambitious scientific assessment of the mountain. The National Geographic Society, working in partnership with Tribhuvan University, the Government of Nepal, and funded by Rolex, launched the two-month expedition, which ultimately involved more than 30 scientists conducting fieldwork at various elevations on the mountain as well as across the rugged Khumbu Valley.

If you follow the weather closely, you, too, can make a reasonable forecast. Radar and satellite images showing precipitation and cloud cover are now common on television, online, and in the daily newspaper. Weather balloons and AMDAR instruments gather information about temperature, pressure, humidity, and wind from very high levels in the atmosphere. Meteorologists input the data to computers and use it to map atmospheric winds and jet streams. They often combine this with data about temperature, humidity, and wind recorded at ground level. These complex weather maps using geographic information system (GIS)technology can calculate how weather systems are moving and predict how they might change.

We saw the line of people ahead of us,” Perry said, “and realized what we were up against. When we moved to May 23rd, that just put us in the middle of two very busy summit days.” The instructions that came with the model are far from great, but thankfully, setting up was not too difficult and there are tutorials available online, though you shouldn’t really need them anyway. Meteorology is the science of forecastingweather. Weatherforecasting has been important to civilizations for thousands of years. Agriculture relies on accurateweatherforecasting: when to plant, when to irrigate, when to harvest. Ancient cultures—from the Aztecs of Mesoamerica to the Egyptians in Africa and Indians in Asia—became expert astronomers and predictors of seasonal weather patterns.It wasn’t totally unexpected. We had seen some of this in the icefall and going up the Lhotse Face,” Perry reflected. “But it was frustrating for the Sherpa team because we couldn’t all just unclip and zip past these people. The slower you move, the colder you get.” Off shortly to replace the Duracell’s with Energizer Lithium’s. Hopefully these will last till next weekend, by which time the replacement should have arrived.
