Climate Variability: Pacific - North American Teleconnection Pattern

This pattern, known as the Pacific-North American teleconnection pattern or PNA, influences regional weather by affecting the strength and location of the East Asian jet stream, and subsequently, the weather it delivers to North America. A pattern of higher-than-average pressure in the vicinity of Hawai'i and over the mountainous region of western North America, and lower-than-average pressure south of Alaska and over the southeastern United States defines the positive phase of PNA.

This pressure pattern enhances the strength of the mid-latitude jet stream as it moves over the Pacific Ocean from eastern Asia. Climate Oregon - temperature, rainfall and average.

The Aurora Borealis (The Northern Lights) – Everything you need to know

After several years of research, kilometers travelled, multiple destinations visited, dark drives down foreign icy roads, snow storms, disappointment, exhilaration, several failures but more successes, here is my two cents on everything Aurora Borealis First off, before I start I wanted to elaborate a little on the above. I’ve always held a certain fascination for the Northern Lights. My earliest memory was a documentary on the Discovery channel on Antartica when I was around 12 years old.

I found them ethereal and magical and straight away wanted to know more about them and see them. Being a 12 year old though has it’s drawbacks =) Being completely at the mercy of my parents destination wishlist meant that I wouldn’t really get to chase this dream until a little later on. SWPC Tips on Viewing the Aurora. NOAA / Space Weather Prediction Center Being able to see the Aurora depends mainly on two factors, geomagnetic activity (the degree of disturbance of the earth's magnetic field at the time) and your geographic location.

Spectacular Auroras Could Be Visible In Parts Of The US This Weekend

Aurora borealis, produced by coronal mass ejections, will be visible throughout the northern U.S. Friday and Saturday night. The solar flare that erupted on Wednesday will be putting on a spectacular show this weekend, when the second of two coronal mass ejections - charged gases shooting out from the sun - is projected to arrive. These powerful solar storms will produce auroras that will potentially be visible in the central and northeastern U.S. during the late hours on Friday and Saturday, according to Tony Phillips at Here's a helpful AccuWeather map of where the aurora will appear: Northern Lights May Ignite in Northeast, Central US Skies: Where to See Rare Show. Northern Lights May Ignite in Northeast, Central US Skies: Where to See Rare Show By Samantha-Rae Tuthill, Staff Writer September 12, 2014; 10:17 AM ET Stargazers could be in for a rare display Friday night as an Earth-directed solar flare ignites the northern lights, also known as the aurora borealis, in the United States.

Northern Lights May Ignite in Northeast, Central US Skies: Where to See Rare Show

As a result of the flare's direction and strength, the dazzling light display could reach as far south as Maryland in the East and down over Nebraska farther west. According to Astronomer Hunter Outten, the flare is ranked as an X-class, or the highest class for a solar flare. A coronal mass ejection (CME), or a cloud of charged particles released from solar activity, is expected to induce a geomagnetic storm in Earth's atmosphere, around midday Friday.

"There will be a pretty good chance to see the northern lights [Friday] because of the first geomagnetic storm Thursday night," Outten said. Back-to-Back Sun Storms May Supercharge Earth's Northern Lights. Powerful solar flares from the sun this week may amplify the northern lights displays over parts of the northern United States through the weekend, space weather scientists say.

The forecast for potentially supercharged auroras comes after powerful solar storms fired off eruptions of solar material, first on Monday (Sept. 8), then again on Wednesday (Sept. 10). During Wednesday's solar flare, the sun unleashed a major X1.6-class flare directly at Earth. While aurora activity could spike overnight tonight (Sept. 11), the best chance of strong northern lights displays along the northern U.S. states will be Friday night.

The Storm Events Database contains the records used to create the official NOAA Storm Data publication, documenting: The occurrence of storms and other significant weather phenomena having sufficient intensity to cause loss of life, injuries, significant property damage, and/or disruption to commerce; Rare, unusual, weather phenomena that generate media attention, such as snow flurries in South Florida or the San Diego coastal area; and Other significant meteorological events, such as record maximum or minimum temperatures or precipitation that occur in connection with another event.

The database currently contains data from January 1950 to November 2018, as entered by NOAA's National Weather Service (NWS). Due to changes in the data collection and processing procedures over time, there are unique periods of record available depending on the event type. Maps & Data.

You can select stations by first selecting a network in the "Select network" pull-down and then typing some or all of a station id or station name in the "Enter station(s)" box. Once a search string is entered, a list of the first 10 matches will be provided. If the first character entered is a digit, it will look for station ids that match, otherwise it will look for station names that match. Click on a station to add it to the list of selected stations.
