Learn about the weather and the climate. Our instructional videos offer in-depth discussions of key meteorological topics.
A fast-moving low pressure system dropping southeastward from Canada into the Northeast US during the winter season is commonly referred to by meteorologists as a "clipper" and this weather phenomenon is described in detail in this video discussion.
The North Atlantic Oscillation (NAO) is an important wintertime "teleconnection" for the Mid-Atlantic region. Knowledge of the NAO index is critical for weather forecasting in this region and it is described in detail during this video discussion.
The Pacific Ocean is by far the largest ocean in the world and knowledge of temperature and pressure patterns there are crucial. Similar to the North Atlantic Oscillation (NAO), the Pacific Decadal Oscillation (PDO) is another important "teleconnection" for the Mid-Atlantic region.
The weather plays a crucial role in the distance a baseball can travel and this video describes in details the many parameters involved such as wind speed, humidity and temperature.
Hurricane Sandy (October 2012) generated a damaging storm surge for parts of the New Jersey coastline, but left other areas without serious problems. The processes involved with a storm surge are described in this video discussion with a focus on Hurricane Sandy.
Upper atmosphere winds are crucial to weather forecasting and occasionally there are "blocking" patterns that produce very slow movement of surface-level systems. The "omega" block is one such type of atmospheric wind flow that can grind surface systems to a halt and it is described in detail in this video.
It can be quite useful for weather forecasters to compare past weather events to current events if their are some similarities in the overall atmospheric pattern. Indeed, "analog forecasting" was a useful tool in the prediction of the "Blizzard of February 2014" that pounded the Mid-Atlantic region.
