Pacific Decadal Oscillation Index (PDO) NAO Index | AO Index | PDO Index | PNA Index | AMO Index | Nino 3.4 | QBO Index Pacific Decadal Oscillation Index (PDO) The Pacific Decadal Oscillation (PDO) is often described as a long-lived El Niño-like pattern of Pacific climate variability (Zhang et al. 1997). As seen with the better-known El Niño/Southern Oscillation (ENSO), extremes in the PDO pattern are marked by widespread variations in the Pacific Basin and the North American climate. The (PDO) is a pattern of change in the Pacific Ocean's climate. The PDO is detected as warm or cool surface waters in the Pacific Ocean, north of 20° N.
During a "warm", or "positive", phase, the west Pacific becomes cool and part of the eastern ocean warms; during a "cool" or "negative" phase, the opposite pattern occurs. As mentioned above, the extreme phases of the PDO have been classified as being either warm or cool, as defined by ocean temperature anomalies in the northeast and tropical Pacific Ocean.

Don’t Expect The Facts From Michael Brune. By Paul Homewood The Sierra Club’s Michael Brune was on CNN yesterday, in debate with Climate Depot’s Marc Morano. Not for the first time, he came out with fact free claims about how extreme weather was on the increase. We know that the extreme weather events that we’re seeing, the record wildfires, the record droughts, the extreme storms that we’re seeing, the hurricane that we saw with 1,000-mile diameter that hit the eastern seaboard late October of last year, are precisely what scientists have said would be the cause of global warming and climate change. He made similar claims on the Piers Morgan show in January, which I showed at the time to be false. But let’s go through Brune’s claims again and see how they have no substance. Drought And precipitation is trending upwards, based on hydrological years, (Oct to Sep). According to NOAA:

We talk a lot about El Niño and La Niña at the ENSO blog, but there are other phenomena that garner interest among scientists, even if they do not have the same brand recognition as El Niño. So while we wait for a potential La Niña (forecaster checks watch), this blog post will take us on a first date with a sea surface temperature (SST) pattern in the North Pacific Ocean called the Pacific Decadal Oscillation or the PDO.
(Tony already provided our meet cute with the PDO.) First identified in the late 1990s (Mantua 1997), the PDO is the most significant year-round pattern in monthly SSTs across the North Pacific. Similar to ENSO, the PDO has two states – warm and cold – and involves various other aspects of the climate system. Unlike ENSO, the PDO isn’t one climate phenomenon. What we call the PDO is instead an aggregation of mostly independent processes. What does the PDO look like? What makes up the PDO Neapolitan sundae?

NRCS National Water and Climate Center | Home. • Mount Rainier Statistics - www.sTePhaBeGg.com. One morning I woke up wondering how many people climb Mt. Rainier each year. I got kind of carried away, and two days and several colorful pie charts and graphs later, I decided I had answered my question sufficiently.
The result was the following statistical study.....The National Park Service continually collects statistical data pertaining to climbing Mt. Rainier. This data is presented on their website in query tables. In looking for a way to fulfill my incessant need to play around with statistical data, I scrounged as much data as I could from the query tables, and used it to create the colorful graphical display of pie charts and graphs on this page. I've left most of the statistical interpretation/conclusions up to the viewer, so just browse around and look at whatever statistics pique your interest.
Website I used for most data: Important Note: I did this study in February 2011, so I used the data available at that time. Since 2002, Mt. Mt. Where Have All The Glaciers Gone? The best measure of overall climate for glaciers is the Pacific Northwest Index developed by Curtis Ebbesmeyer (PNI DATA) at the University of Washington. This index is based on the annual temperature at Olga, WA, Annual precipitation at Cedar Lake WA and March 15 snowpack depth at Mt. Rainier WA. The chart below indicates the variation of the PNI with time. It has been consistently high since 1977.
The PDO (Pacific Decadal Oscillation was identified to be the main atmospheric circulation controller of Pacific Northwest Climate by Mantua and Hare at University of Washington. Note the trendline through time of PDO and PNI in the five year moving average are relatively close. Rising and high values of PNI result in glacier retreat. Mean PNI for the 1920-1944 period was 0.42 triggering glacier retreat. Pacific Northwest Index (PNI) | Columbia Basin Research. Summary The Pacific Northwest Index (PNI), developed by Ebbesmeyer and Strickland (1995), is a terrestrial climate index useful for studying climate effects on salmon productivity trends.
It is a composite index that characterizes Pacific Northwest climate patterns in both coastal waters and freshwater habitats. In addition, it is a century-long record. A composite climate index is an effective measurement because many environmental parameters in the Northwest are statistically related to one another; consequently, they may be combined to furnish a broad-scale understanding of the state of the Pacific Northwest environment. The PNI uses three parameters: 1) air temperature at Olga in the San Juan Islands, averaged annually from daily data; 2) total precipitation at Cedar Lake in the Cascade Mountains; and 3) snowpack depth at Paradise on Mount Rainier on March 15 of each year.

Workings of Mother NatureAn Esker is a long, snake-like ridge of glacial till deposited by a stream that ran under or within a glacier. Our planet is one of its kind in the solar system.
Geologists and geographers have charted the course of its physical evolution dating back to the original formation through collision with suspended matter in the system. We know of mountains and plains, plateaus and rivers, and everything in between. That obviously includes how these landforms were formed. But as we know now, the physical properties of the Earth are constantly evolving and reshaping themselves, and this process can span centuries or even take days. One of the interesting formations that is found is that of a glacial till.
When we think of tilling, we think of agricultural methods like digging, overturning, and stirring. So how is glacial till formed, you ask? Glacial till, as we described earlier, consists of sedimentary deposits made by the movement of glacial ice. Tillite Ablation Tills. Fluvioglacial Processes And Landforms.

Today's theme: What are glaciers, and how do they change a landscape? Use the following GIFs to help answer any questions you have during the reading for Day 057 HW (pp. 298-302). "Glaciers are like the Incredible Hulk--they're big, strong, and will break everything in sight. "-Mr. 057.1 What is a glacier, what does it do, and how does it move?
Rivers definitely help to carve out and change a landscape, but nothing is as big and powerful as a glacier, which is a large "river" of moving ice. Glaciers are powerful because of their size and weight. Glaciers can be large ice sheets like those over Greenland and Antarctica. 057.2 What is a valley glacier?
Not all glaciers are ice caps or ice sheets. The true power of glaciers come from their transporting of sediments of all sizes in the ice flow. 057.3 What are U-shaped valleys? 057.4 What are glacial striations (grooves) and plucking?

"Glaciers are like the inside of my backpack--big and kinda messy. "-Mr. Gruszka 058.1 What is glacial till, and how can we recognize it? We have seen how rivers seem to be very neat about how they deposit their sediments by size. One type of glacial deposit is called a moraine. . 🔑 The important thing to remember about moraines is that the sediments are all mixed up. 058.2 What is an outwash plain?
At the end of the glacier, where the moraine forms, lots of water washes away the different sediments to new positions. Because the stream velocity where the glacier melts, small pebbles and even some cobbles can be moved out from the moraine. VUDEEVUDEE'S GEOGRAPHY BLOG: THE STUDY OF GLACIERS. Glaciers are large, slow moving, masses of ice, that deform and move down slope under their own weight. Glacial landscapes are distinctive due to glaciers being powerful agents of both erosion and deposition.
Approximately 10% of the earth's surface is covered by glaciers. Large areas of glacial ice are found in high latitude areas such as Greenland and Antarctica, however glaciers are also found in areas of high altitude (e.g. the Rockies). The distribution of glaciers is affected by both latitude and altitude. These regions also have high albedo surfaces (snow reflects large amounts of solar radiation back into space). Glaciers are found in areas of high-altitude (mountainous regions), such as the Alps, Himalayas and the Andes, due to very low temperatures. Local scale factors such as relief and slope aspect (direction faced by the slope) also affect the distribution of glaciers.
The Movement of Glaciers Variations in Glacier Movement Glaciers do not move in a uniform way. 1. 2. 3. » The Great Missoula Floods. Exhibit by: Jessica Sterling Ice Dammed Lake Missoula The Portland region owes its rich agriculture and beautiful geography to a series of massive ice-age floods that burst from an ice dam about 15,000 years ago, stripped soil from eastern Oregon and Washington, ripped cliff walls off the Columbia gorge, and floated house-sized boulders downstream. Simplified map of Lake Missoula, the scablands and the temporary lakes alongside the margin of the late Devensian ice sheet During the last great stage of the Ice Ages, the Cordilleran ice sheet extended south along the Canadian Rockies and the Coast Ranges, and just reached into the United States.
Ice reached thicknesses of over 3,000m (over 9,842 ft, or 5 ½ World Trade Center towers). One of the greater ice streams, the Purcell ice stream developed in the fault-bound trench (of the same name), and gathered ice and snowfall.
