The Saharan Air Layer (SAL)

I’d like to tell you about a member of the weather family: The Saharan Air Layer, or SAL for short. SAL usually gets alot of attention this time of year (August) as weather folk look toward the West Coast of Africa for tropical storm and hurricane development.  Now,  just like any other family member, SAL has both positive and negative qualities, depending on perspective of course. But to first understand SAL, we must first understand the geography and environment from which SAL originates: The Saharan region of Africa. In the equatorial tropics, the average wind is out of the northeast,...

Updated 2016 Atlantic Hurricane Season Forecast and August Climatology

Most Active Hurricane Season Since 2012 Believe it or not, we are already 2.5 months into the 2016 Atlantic hurricane season, which runs from June 1st to November 30th. So far, the 2016 hasn’t been all that impressive or too newsworthy, but in the words of NOAA, “it only takes one to change your community forever.” Earlier this week, the 6th named storm of the 2016 Atlantic Hurricane Season developed. Take a look at Fiona from early Friday in the infrared satellite loop below. Interestingly, this is the earliest we’ve seen 6 named storms since 2012! Note that there were...

2016 Perseids Photos

The Perseid meteor shower of 2016 peaked overnight on August 11th/12th and there have been some great photos going around of the show. The National Weather Service in Seattle set up a few cameras on their roof to capture the show. Here’s what they saw: 2016 Perseids timelapse from the rooftop of the NWS Seattle office. Here are a few stills they managed to capture: A few #PerseidMeteorShower photos from the roof of NWS Seattle overnight. #wawx — NWS Seattle (@NWSSeattle) August 12, 2016 It also seemed like a decent show in Mount Adams, Washington.

2016 Perseids Guide

It’s that time of the year! Skywatchers rejoice! The Perseids are here and it’s predicted to be quite a show tonight. What are the Perseids? Every July and August, the debris field left behind by the Swift-Tuttle comet lights up our sky annually. Pieces of debris heat up as they enter Earth’s atmosphere and result in bright bursts of light. Most of the meteors are only the size of a grain of sand and burn up quickly. The Perseids event is considered the most popular meteor shower of the year and with good reason: it is the most active meteor...

Recreating the Parallax Menu in Aeris Pulse iOS

We’ve had several users of our Aeris Weather iOS SDK ask us about whether the parallax UITableViewCells in the map layer menu of Aeris Pulse was available as part of the SDK, or how we achieved the effect.   Although this menu is not offered as part of our iOS SDK, it’s really easy to implement. There are just a few main steps you need to perform to get this effect working in your own apps. The following code samples are provided using Swift, but can easily be ported over to Objective-C if you haven’t jumped into Swift yet. Generate background images...

Dangerous & Potentially All-Time Record Heat This Weekend In The Southwest

Follow Meteorologist D.J. Kayser on Twitter (@dkayserwx) or on Facebook (Meteorologist D.J. Kayser). It is June, which means it’s time for the summer heat to set in across the country, particularly in the Southwest. While record highs are possible in parts of the central U.S. over the next couple days, the most extreme heat will be held off until this weekend and into early next week in the Southwest, where thermometers will flirt with 120 in spots. This could lead to some areas nearing their all-time warmest temperatures on record. Record Breaking Highs Expected As you can see, blistering heat...

Hurricane Preparedness – Sources of Information

Before hurricane season begins, it’s important to identify sources that you can get accurate and up to the minute information from. The National Hurricane Center (NHC) and the Central Pacific Hurricane Center (CPHC) are the official sources for hurricane forecasts, including track forecasts. These two sources also issue hurricane watches and warnings. Your local National Weather Service (NWS) office provides details into the types of impacts your location can expect from the storm. Emergency managers in your city, county, or state will make the final decisions regarding evacuations. Most of this information can typically be found online. The sources listed...

Kubernetes: Extending Tools To Build New Things

On the Operations Team here at AerisWeather, we use Kubernetes to orchestrate our containerized applications and previously wrote about how much we love using it. Kubernetes and it’s CLI tool, kubectl, help deploy applications to our production environment in a consistent and reproducible manner. We can update high throughput applications in place with rolling updates, view cluster-wide metrics, and see what’s running where. Component integration in a large microservice application can be daunting, but we are able deploy our application with the help of Kubernetes. Emphasis on the “help”. We found ourselves not only integrating parts of our application together, but also parts of our DevOps...

Hurricane Preparedness – Survival Kit

It’s Hurricane Preparedness Week and today’s topic is all about survival kits! It’s very important to keep a basic disaster kit in your house or place of business for a variety of emergency situations. Hurricanes are a little different than other weather events because they usually offer a bit more warning time. People sometimes choose to stay in their homes and ride out the hurricane. In these situations it is especially important to have a survival kit. Whether it’s for a tornado, hurricane, or other event, these kits should all contain the same types of items. A basic kit could...
