Climate Variability - Florida Climate Center. Tropical Cyclone Climatology. Contents Overview A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation.

Tropical Cyclone Climatology

Tropical cyclones rotate counterclockwise in the Northern Hemisphere. They are classified as follows: Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less.Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots).Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher. Tropical cyclones forming between 5 and 30 degrees North latitude typically move toward the west. Tropical Cyclone formation regions with mean tracks (courtesy of the NWS JetStream Online School) Atlantic & Eastern Pacific Climatology The Atlantic hurricane season runs from June 1st to November 30th, and the Eastern Pacific hurricane season runs from May 15th to November 30th.

‘Temperature Anomaly’ is how different the current temperature is from the expected temperature. Source: University of Maine. Temperatures across the Great Lakes and Eastern United States are setting cold temperature records for the first half of February, 2015, according to the Northeast Regional Climate Center. Compared to expected temperatures, it is the coldest region of the planet. And even in absolute terms, parts of the Northeast have been colder than Anchorage, Alaska. However, this cold isn’t everywhere. What is the Gulf Stream? The Gulf Stream is a powerful current in the Atlantic Ocean.

What is the Gulf Stream?

It starts in the Gulf of Mexico and flows into the Atlantic at the tip of Florida, accelerating along the eastern coastlines of the United States and Newfoundland. It is part of the North Atlantic Subtropical Gyre, one of the five major oceanic gyres, which are large systems of circular currents and powerful winds. The Gulf Stream is a western boundary current; its behavior is determined by the North American coastline. The Gulf Stream: Weather and Climate Effects. The Gulf Stream is more than just a single current that attracts an exotic range of fish, and provides quick shortcuts to traveling ships.

The Gulf Stream: Weather and Climate Effects

In fact, its very existence continuously changes the scope of an entire continent's weather patterns and climates. Locally, particularly off the coast of North Carolina, the Gulf Stream can affect water temperatures, providing warmer ocean waters and balmy days, even in the height of fall and winter.

Climate Education Modules for K-12. The Pacific/North American Pattern, or PNA, describes the variation of atmospheric circulation patterns over the Pacific Ocean and North America.

Like other atmospheric circulations, the PNA has the most impact on climate variables during the winter. There are two phases of the PNA, a positive phase and a negative phase. The positive phase usually relates to El Niño and the negative phase to La Niña, however there is a weak connection between the PNA and ENSO. Index. General atmospheric circulation. The cold front of this mid latitude cyclone spawned several fatal tornados on April 28, 2011.

PNA = 0,25 x [Z (20°N, 160°W) - Z (45°N, 165°W) + Z (55°N, 115°W) - Z (30°N, 85°W)] where Z names the average of the anomaly of each month following the basis period of 1950-2000 500 hPa geopotential. where Z * () denotes monthly mean 500 mb height anomaly that is obtained by subtracting the calendar mean value for each month during 1950-2000 base period.


Cloud History, Cloud Thinking — Cloud Index — James Bridle. In 1884 the art critic and social thinker John Ruskin gave a series of lectures at the London Institution entitled The Storm-Cloud of the Nineteenth Century.

Cloud History, Cloud Thinking — Cloud Index — James Bridle

Over the evenings of the 14th and 18th of February he presented an overview of descriptions of the sky and clouds drawn from Classical and European art, as well as the accounts of mountain climbers in his beloved Alps, together with his own contemporary observations of the skies of Southern England in the last decades of the Nineteenth Century. What Ruskin called “plague-cloud” as well as storm-cloud “never was seen but by now loving, or lately, living eyes... There is no description of it, so far as I have read, by any ancient observer. Neither Homer not Virgil, neither Aristophanes nor Horace, acknowledges any such clouds among those compelled by Jove. Microclimate - Climate, Microclimates, Climates, and Altered. Climate microclimates climates altered Climate is the set of characteristic temperatures, humidities, sunshine, winds, and other weather conditions that prevail over large areas of space for long periods of time.

U.S. Koppen-Geiger climate classification (2000 - 2100) The CSIRO Mk3 climate system model contains a comprehensive representation of the four major components of the climate system (oceans, land surface, atmosphere and sea-ice), and in its current form is as comprehensive as any of the global coupled models available worldwide. The major aim in the development of the CSIRO Mk3 climate model has been to provide a coupled atmosphere-ocean system that gives a significantly improved representation of the current climate relative to the prior model generations The CSIRO Mk3 model will be used to investigate the dynamical and physical processes controlling the climate system, for multiseasonal predictions, and for investigations of natural climatic variability and climatic change.

A1 scenario family The A1 scenario family describes a future world of very rapid economic growth, global population that peaks in mid-century and declines thereafter, and the rapid introduction of new and more efficient technologies. A2 scenario. Interactive United States Koppen-Geiger Climate Classification Map. Koppen climate classification. Köppen climate classification, widely used, vegetation-based empirical climate classification system developed by German botanist-climatologist Wladimir Köppen.

His aim was to devise formulas that would define climatic boundaries in such a way as to correspond to those of the vegetation zones (biomes) that were being mapped for the first time during his lifetime. Köppen published his first scheme in 1900 and a revised version in 1918. He continued to revise his system of classification until his death in 1940. Other climatologists have modified portions of Köppen’s procedure on the basis of their experience in various parts of the world. Köppen’s classification is based on a subdivision of terrestrial climates into five major types, which are represented by the capital letters A, B, C, D, and E.

As noted above, temperature defines the other four major climate types. User:Me ne frego.

Local Wind Patterns. Wind is defined as air moving horizontally over the Earth’s surface. Air motions can also be vertical, but these are known by other terms, such as updrafts or downdrafts. Wind direction is identified by the direction from which the wind comes—a west wind blows from west to east, for example. GROLIER ONLINE ATLAS. Chapter 7: Introduction to the Atmosphere.

CHAPTER 4. ATMOSPHERIC TRANSPORT. We saw in chapter 3 that air motions play a key role in determining the distributions of chemical species in the atmosphere. These motions are determined by three principal forces: gravity, pressure-gradient, and Coriolis. We previously saw in chapter 2 that the vertical distribution of mass in the atmosphere is determined by a balance between gravity and the pressure-gradient force; when these forces are out of balance buoyant motions result, which will be discussed in section 4.3 .
