Scientists Are Decoding Mechanism For Long-term Climate Fluctuations In The Atlantic
2013-07-25 10:29:13

Helmholtz Centre for Ocean Research Kiel (GEOMAR) Why does hurricane activity vary from decade to decade? Or rainfall in the Sahel region? And why are the trans-Atlantic changes frequently in sync? A German-Russian research team has investigated the role of heat exchange between ocean and atmosphere in long-term climate variability in the Atlantic. The scientists analyzed meteorological measurements and sea surface temperatures over the past 130 years. It was found that the ocean...

Antarctic Cloud Cover Caused Glitch In Tropical Rainfall Model

April Flowers for redOrbit.com - Your Universe Online One would not assume that cloud cover over Antactica's Southern Ocean could cause rainfall in Zambia or the tropical island of Java. New research from the University of Washington, however, finds that a phantom band of rainfall just south of the equator that does not occur in reality is caused by poor simulation of the cloud cover thousands of miles farther to the south. This illusionary band of rainfall is one of the most persistent...

The vagaries of South Asian summer monsoon rainfall impact the lives of more than one billion people. A review in Nature Climate Change (June 24 online issue) of over 100 recent research articles concludes that with continuing rise in CO2 and global warming, the region can expect generally more rainfall, due to the expected increase in atmospheric moisture, as well as more variability in rainfall. In spite of the rise in atmospheric CO2 concentration of about 70 parts per million by volume...

As ESA's SMOS mission nears the end of its commissioning, a new network will provide harmonized global datasets of soil moisture measurements collected from the ground, ensuring the data received from space are as accurate as possible. Making sure data delivered from space are accurate is a crucial aspect of any Earth observation mission. One way of achieving this is to take in situ measurements on the ground and compare them with the data being acquired by the satellite orbiting above....

Earth has a limited amount of water that recycles itself in what is called the "Ëœwater cycle'. Climate change, weather and human life are highly affected by changes in this continuous, interconnected cycle. Observing and monitoring the key variables governing the global water cycle is essential to our understanding of the Earth's climate, forecasting our weather, predicting floods and droughts, and improving water management for human use. Recent advances in Earth observation (EO)...

Australian scientists say they have determined pollution from Asia, Europe and North America is causing climate change in the Southern Hemisphere. Researchers at Australia's Commonwealth Scientific and Industrial Research Organization said they used a climate model that included the effects of tiny particles called aerosols produced primarily in North America. The study, led by Leon Rotstayn, principal scientist at the Center for Australian Weather and Climate Research, suggests aerosols can...

New research announced at the international Water in a changing climate science conference in Melbourne 24-28 August, implicates pollution from Asia, Europe and North America as a contributor to recent Australian rainfall changes. Australian scientists using a climate model that includes a treatment of tiny particles - or aerosols - report that the build up of these particles in the northern hemisphere affects their simulation of recent climate change in the southern hemisphere, including...

NASA scientists have detected the first signs that tropical rainfall is on the rise with the longest and most complete data record available. Using a 27-year-long global record of rainfall assembled by the international scientific community from satellite and ground-based instruments, the scientists found that the rainiest years in the tropics between 1979 and 2005 were mainly since 2001. The rainiest year was 2005, followed by 2004, 1998, 2003 and 2002, respectively. "When we look at the...

NASA -- A NASA study is offering new insight into how the Earth's water cycle might be influenced by global change. In recent years, scientists have warned that the water cycle may be affected by temperature changes, as warmer temperatures can increase the moisture-holding capacity of air. The global water cycle involves the transfer of water molecules between the Earth's land masses, cryosphere, oceans and atmosphere. It's a gigantic system powered by the sun, fueling a continuous exchange...

Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...

Incoming Solar Radiation Impacts By Various Weather Cycles

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
