Satellite Signals from Space: Smart Science for Understanding Weather and Climate
Want to know about COSMIC, and how satellite signals can provide information about Earth's atmosphere? This video provides anyone interested in the topic with a brief overview of the Constellation Observing System for Meteorology, Ionosphere, and Climate, called COSMIC. Targeted to students and teachers in Grades 5-9 but accessible to anyone, the video introduces the latest COSMIC mission (COSMIC-2), which uses satellites orbiting near Earth to measure how the atmosphere affects signals from global positioning system (GPS) satellites high above the surface. This technique is called radio occul ...

Want to know about COSMIC, and how satellite signals can provide information about Earth's atmosphere? This video provides anyone interested in the topic with a brief overview of the Constellation Observing System for Meteorology, Ionosphere, and Climate, called COSMIC. Targeted to students and teachers in Grades 5-9 but accessible to anyone, the video introduces the latest COSMIC mission (COSMIC-2), which uses satellites orbiting near Earth to measure how the atmosphere affects signals from global positioning system (GPS) satellites high above the surface. This technique is called radio occultation and measures the bending of the GPS signal in the atmosphere. The observations offer scientists very accurate information to improve weather forecasts, especially for tropical events such as hurricanes. COSMIC also helps scientists monitor a part of Earth's upper atmosphere called the ionosphere and provides long-term records for understanding Earth's climate. This video is part of the UCAR Center for Science Education's Satellites and Weather Teaching Box.

The Sahel Drought Mechanism: insights from two contrasting extreme events
The Sahel drought mechanism: insights from two contrasting extreme events during boreal summer July-August-September (JAS) is investigated in this study using the standardized precipitation index (SPI). Empirical orthogonal function (EOF) and composite analyses were deployed in this study, where the global precipitation climatology center (GPCC) rainfall data is used. The SPI shows large widespread decreasing rainfall trend in the Sahel in the mid-1980s; thereafter, Sahel rainfall have recovered somewhat through the late 1990s, even though the drought conditions have not ended in the region. A ...

Variability of Benin JJAS Precipitation associated with MAM SST Anomaly in the Atlantic Ocean
Precipitations vary consistently in Benin from 1981 to 2010. The present study reveals that the variation of Benin JJAS precipitation is positively correlated to MAM Sea Surface Temperature (SST) in Atlantic Ocean with correlation coefficient more than 0.7. When the SST is higher (lower) in the Atlantic Ocean, precipitation over Benin tends to be above (below) normal. The years 1988, 1989, 2003, 2007 and 2008, were wet with 1988, 2003, 2008 high SST over Tropical Southern Atlantic Ocean (STAO) while the years 1982, 1983, 1992 and 1997 formed the dry years with low SST over Tropical Southern At ...

Satellite-Derived Climatology Products for Monitoring Convection Over West and Central Africa
A weather forecaster’s knowledge of climatology is important to the success of a forecast, especially where convection is involved. That’s particularly true over Central and West Africa where convection has a strong diurnal cycle and usually develops over particular geographic regions and during specific time intervals. The lesson describes satellite-derived cloud climatology products and several global instability indices, all of which can be integrated with other products to forecast convection. Although the lesson uses examples of climatology products from specific months, it makes the full ...

Extreme High Swell Events on the Moroccan Atlantic Coast
High swell events can develop far from the coast under cyclonic conditions, and take several days to travel to land. If early warnings are not issued, they can take an area by surprise and have a devastating impact. This lesson aims to improve the ability of marine forecasters to forecast extreme marine events related to high swells. It does so by providing background information on winds and waves, and presenting a process for monitoring and forecasting high swell events using a variety of data. These include ASCAT scatterometer wind data and the ECMWF Extreme Forecast Index (EFI) product, wh ...

Climate change in the Himalayas : current state of knowledge
This paper reviews the literature on the potential biophysical and economic impacts of climate change in the Himalayas. Existing observations indicate that the temperature is rising at a higher rate in Nepal and Chinese regions of the Himalayas compared with rest of the Himalayas. A declining trend of monsoon in the western Indian Himalayas and an increasing trend in the eastern Indian Himalayas have been observed, whereas increasing precipitation and stream flow in many parts of Tibetan Plateau are noted. Glaciers in both the eastern and western Himalayas are mostly retreating, but the majori ...

Climate change and water resources in the tropical Andes
Climate change will without a doubt affect future access to clean drinking water, as well as to water for sanitation, irrigation and agriculture, mining operations, and hydro power production in the tropical Andes. Social, economic and environmental conflicts surrounding the struggle for control over water will be exacerbated in areas where water scarcity is juxtaposed with rapidly growing water demand due to population pressure and expanding economic activities. This paper describes the challenges surrounding current and future water use in the tropical Andes by first reviewing the modern and ...

66 - February 2012 - A method for estimating the sea-air CO2 flux in the Pacific Ocean
is an issue of 気象研究所技術報告. Meteorological Research Institute, 2012In this technical report, we describe a newly developed method for evaluating monthly fields of oceanic pCO2 and the subsequent temporal variations of the sea-air CO2 flux over extensive regions of the North and South Pacific by using synthesized observational data. The application of this method is expected to contribute to understanding of future changes in the ocean carbon sink and the ocean's role in controlling the rate of atmospheric CO2 increase.

Arctic Meteorology and Oceanography
Diminishing sea ice has opened the Arctic to navigation and operations like never before. Forecasters are increasingly predicting weather in support of those operations. This module is intended to provide forecasters with a brief introduction to the Arctic, including its geography, climatology, and the forecast problems they are likely to encounter. The module follows a U.S. Coast Guard Cutter on a voyage from Dutch Harbor, in the Aleutian Islands, to Barrow, on the north coast of Alaska. Various topics are addressed along the way in a series of short, stand-alone lessons.
