Coastal Climate Change
As climate changes, dynamic coastal regions are experiencing a wide range of impacts. Sea levels, ocean acidification, sea surface temperatures, ocean heat, and ocean circulation have all been changing in ways unseen for thousands of years. Arctic sea ice melted significantly more during summers in the last 30 years, and storms are intensifying. Coastal ecosystems stand to be damaged, and coasts will likely erode from rising sea levels, intensified storm surges, and flooding that climate change may amplify. Coastal communities will need to prepare adaptation strategies to cope, and many who li ...
Space Weather: Welcome, SEC
This video presentation welcomes the Space Weather Prediction Center, formerly known as the Space Environment Center or SEC to the National Weather Service (NWS) as an operational entity of the National Centers for Environmental Prediction (NCEP) family. Describing the ways in which space weather affects global communications and power resources, it demonstrates the importance of space weather forecasting as a part of the NWS family of services. With the inclusion of SWPC, the NWS now provides environmental understanding from the sun to the sea.
Satellite Feature Identification: Inferring Three Dimensions from Water Vapour Imagery
We think in three-dimensional space and a fourth dimension, time. Therefore, we should think about the atmosphere in similar terms. However, we are often stuck with two-dimensional maps. Water vapor imagery can help us break out of that flatland and move to more dimensions. This imagery holds so much under-utilized potential. We can actually see three-dimensional structures evolving in near-real-time. And if we have a good handle on the current three-dimensional structure, we can then use NWP to its fullest as a verification/interrogation instrument for our 3D mental model. Come see the atmosp ...

It focuses on the major aspects of synoptic and mesoscale weather patterns, hazards to aviation and maritime operations, geography, oceanography, and climatology. The “Geography” Unit covers major political boundaries, cities, ports, topographical features, rivers, and seismicity. The “Oceanography” Unit includes major bathymetric features, mean sea surface temperature, vertical temperature profiles, salinity and velocity, ocean currents, and tidal ranges. The “Climatology” Unit covers the seasonal climatology of ...
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 ...
Mei-Yu Front, Part 1: Ingredients for Heavy Precipitation and the Forecast Process in Taiwan
This lesson (available in Traditional Chinese) introduces the Mei-Yu Front characteristics and forecasting methodology used by the CWB to forecast precipitation over Taiwan. The lesson discusses the Mei-Yu Front's three-dimensional structure, lifting mechanisms, precipitation patterns and includes cases to help learners practice determining the possible area of heavy rainfall.
ASMET: Flooding in West Africa
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, standa ...

Low-Level Coastal Jets
Low-level coastal jets occur along many coastlines. Winds may exceed 35 knots and lead to high waves and significant low-level vertical wind shear. Thus, low-level coastal jets present a hazard to both marine and aviation operations in the coastal zone. This core module describes the features of coastal jets and explores the conditions under which they form. Like other foundation modules in the Mesoscale Primer, this module starts with a forecast scenario and concludes with a concise summary and a final exam. By the end of this module, you should have sufficient background to diagnose and fore ...
