3 - Nuclear Change
Conditions of Use:
Remix and Share
Rating

In the Nuclear Change unit, students will learn about nuclear change through examining the phenomena of radon. Three questions that students will answer at the end of the unit are:  is air we breathe in buildings radioactive and what is Radon and how does it affect health? First, student will investigate what is radon. Next, students will build a atom to learn how atoms can exist in stable and unstable isotopes. Students learn about types of radiation and then complete an inquiry about half-life of atoms. Half lifes can be used to map geology and assess danger timelines. Next, students learn how nuclear change occurs through fusion or fission. Additionally, students learn that the high energy released has military/commercial uses, and the legacy of cosmic, geologic and human events and activities has impacted where radioactivity exists on the earth. Students end the unit with a cumulative Socratic seminar about Hanford while assessing risk and benefits of using nuclear reactions and recovering sites contaminated by radioactive materials is complex. At the end of the unit students discuss the following question: should parts of the Hanford Nuclear Reservation be opened as a recreation area or returned to Native Americans?

Rating

A century of full-fledged industrialism in America had taken its toll on the environment. Concerned citizens began to appeal in earnest to protect more of the nation's wilderness areas. Emissions into the atmosphere were creating smoggy haze rings above many metropolitan centers. Trash was piling up. Many Americans felt free to deposit waste from their increasingly disposable society along the sides of the roads. In the climate of social activism, the 1960s also became a decade of earth action.

In August 2008, the "Mountain Weather Workshop: Bridging the Gap Between Research and Forecasting" was held in Whistler, BC, Canada. It was sponsored by the American Meteorological Society, UCAR/COMET, and the Meteorological Service of Canada. The workshop brought together researchers, faculty, students, and operational forecasters. Its primary goals were to help provide a better understanding of the state of the science of mountain meteorology from both a research and an operational perspective, and to discuss ways of improving interaction between the research and forecasting communities. The workshop consisted of lectures by distinguished speakers covering numerous topics related to weather in complex terrain. This webcast collection contains recordings of the presentations from the workshop.

ASMET: 2009 Drought in East Africa
Conditions of Use:
Read the Fine Print
Rating

The module examines the 2009 drought in the Greater Horn of Africa (GHA), focusing on conditions in Kenya. The module begins by reviewing drought conditions in the years leading up to 2009. From there, it examines the seasonal climate forecast for the beginning of 2009 and see what it portends. Satellite products are used to study rainfall performance throughout the year and its impact on the drought situation. Finally, the module describes the climate oscillations that can impact drought in the GHA and identifies patterns that were present in 2009 and contributed to its severity. By the end of the module, weather forecasters and students should have a better understanding of drought and the tools available for its early detection and monitoring.

ASMET 7: Convective Weather and Aviation in West and Central Africa
Conditions of Use:
Read the Fine Print
Rating

The hazards associated with convective systems present some of the most dangerous conditions encountered by aircraft and pose many challenges to aviation operations. When convection is forecast to develop, aviation forecasters are required to issue a series of warning messages and other meteorological aeronautical products to various members of the aviation community. This lesson teaches these forecasters how to produce the products, doing so in the context of a case study in which learners assume the role of aeronautical forecaster on duty at the airport in Niamey, Niger on a night when convection develops. The lesson is one of three aviation weather case studies developed by the ASMET team to improve aviation forecasting in Africa.

ASMET 7: Detecting Clear Air Turbulence: South African Case Study
Conditions of Use:
Read the Fine Print
Rating

Turbulence is a major concern for the aviation industry. It often goes undetected in cloud-free areas, catching pilots off guard when they fly into it. Turbulence can injure passengers and crew, and cause structural damage to aircraft. This makes it critical for aviation weather forecasters to closely monitor the atmosphere for signs of turbulence and issue special warnings when it is likely to be present. This lesson helps prepare forecasters for these tasks by providing general information about turbulence and showing them how to detect it using satellite imagery, tephigrams, and NWP products. The latter is presented in the form of a case study in which learners assume the role of aviation forecaster at Cape Town International Airport (South Africa), and need to determine if turbulence is likely to be present along a particular flight path. The lesson is intended for aviation weather forecasters, general weather forecasters interested in aviation meteorology, and meteorological instructors and students. Note that the lesson is one of three aviation weather case studies developed by the ASMET team to improve aviation forecasting in Africa.

This lesson aims to improve aviation forecasts of fog in the African airspace by teaching forecasters to make more accurate forecasts using satellite imagery, numerical weather prediction, and other available data. A process for diagnosing and forecasting fog is presented and applied to a case over the Nairobi, Kenya region. Learners assume the role of aviation forecaster, analysing various products to determine whether the current Terminal Aerodrome Forecast (TAF) is valid or needs to be amended. The lesson is intended for aviation forecasters, general weather forecasters interested in aviation meteorology, and meteorological forecasting instructors and students. This lesson is one of three aviation weather case studies developed by the ASMET project to improve aviation forecasting in Africa. They also support COMET's Review of Aeronautical Meteorology – Africa online learning curriculum, which provides training that supports the WMO/ICAO competencies for Aeronautical Meteorological Forecasters.

ASMET: Flooding in West Africa
Conditions of Use:
Read the Fine Print
Rating

The rainy season in Sahelian West Africa extends from June to September and is tied to the position of the intertropical front. During this period, mesoscale convective systems (MCSs) often produce significant rainfall that can lead to flooding. This module examines an extreme flooding event that occurred in Ouagadougou, Burkina Faso from 31 August to 1 September 2009. Learners assume the role of forecaster, assessing meteorological conditions to see if an MCS will develop that can lead to heavy rain and flooding. They follow a forecast process that emphasizes the use of satellite data, standard surface and upper-air charts, and model output. The forecast process is tied to a conceptual model of the key features that drive convective activities in West Africa.

Acidic Oceans Prompt Evolution
Conditions of Use:
Read the Fine Print
Rating

It's no secret that greenhouse gases warm the planet and that this has dire consequences for the environment whole islands swallowed up by rising seas, animal and plant species stressed by higher temperatures, and upsets in ecological interactions as populations move to cooler areas. However, carbon dioxide has another, less familiar environmental repercussion: making the Earth's oceans more acidic. Higher levels of carbon dioxide in the atmosphere mean that more carbon dioxide dissolves in the ocean. This dissolved carbon dioxide forms carbonic acid the same substance that helps give carbonated beverages their acidic kick. While this process isn't going to make the ocean fizzy anytime soon, it is introducing its own set of challenges for marine organisms like plankton and coral.
