On Friday, May 11, 2018, a wildfire in the Texas Panhandle played a role in the development of a thunderstorm. This storm eventually evolved into a supercell thunderstorm that tracked into portions of western Oklahoma.Topics: RadarScope | Wildfire |
After a very cold month of April, the pattern has turned markedly warmer during May. While that has generated above-normal cooling demand as portions of the country reach the 90s and portions of the Southwest even reach the 100s, much of the Midwest and Northeast is finally seeing some pleasant weather. There is still usually some heating demand across the northern US in early May, but the warmer weather this month has limited that.
In this second part of the series looking at common non-precipitation radar echoes, we will look at several examples of biological scatter, including birds, bats, and insects. Dual-polarization data is usually the best way to distinguish biological echoes from precipitation, especially in a static image. These types of echoes generally have low a correlation coefficient and high differential reflectivity. The following can help identify what kind of creatures are responsible for specific common patterns of biological echoes in radar data at certain times of the day or year.Topics: RadarScope |
When bringing RadarScope to a new platform, we try to strike a balance between RadarScope’s unique personality and the way customers expect an app to behave on that platform. While features behave similarly across iOS, macOS, Android, and now Windows, the user interface often differs from one platform to the next. With that in mind, let’s take a look at how custom locations are added, managed, and displayed in RadarScope for Windows.Topics: RadarScope |
Spotters and storm chasers can provide a treasure trove of information useful to NOAA National Severe Storms Laboratory (NSSL) researchers by reporting what you see through RadarScope. Tornado sightings are extremely helpful for both warning purposes and research purposes. While it's hard to imagine, not all the tornadoes you see get reported and make it into databases. But one of the most challenging severe storm aspects to capture is hail information.
The General Data Protection Regulation (GDPR) is a regulation by which the European Parliament, the Council of the European Union, and the European Commission intend to improve data protection for all individuals within the European Union (EU).Topics:
Over the past year, I've sought to learn from industry colleagues and clients to achieve a high level of understanding of entertainment weather risk in its current state. I have had conversations with customers, vendors, and insurers to understand better how risk is calculated, where exposure lies, and what we can do to better identify and mitigate.
Usually, meteorologists and other weather observers use reflectivity to identify where precipitation is falling and how heavy it is. However, sometimes radars detect things that are not precipitation (the fancy term for the source of these echoes is “non-hydrometeor scatterers” or “non-meteorological scatterers”). Often, these have an unusual appearance to observers that are used to looking at precipitation, which causes people to ask “what is that?” This series of blog posts will describe several of the most common forms of non-precipitation echoes and how to use RadarScope and sometimes other meteorological data to determine the most likely explanation (usually not bats or aliens, despite the comments in the RadarScope users group on Facebook). Many of these features will only be visible on RadarScope with Expert Mode turned on, as they have relatively low reflectivity values.Topics: RadarScope |
Air is in motion all around us, moving both vertically and horizontally. Whether clouds or precipitation form partially depends on whether air rises or sinks. When air descends, this is called subsidence, and it can have significant implications on the weather that you observe.Topics: WeatherOps |
The location of troughs and ridges can play an essential role in a region's weather. Weather observations above the ground are collected by weather balloons. Data from one a single site are plotted on a sounding, but an upper air chart can show information from multiple observation sites.Topics: WeatherOps |
