Twenty-seven or younger? Then you’ve never experienced a month in which the global temperature has been colder than average, according to the latest data from the U.S. National Oceanic and Atmospheric Administration.
Using the same tech Martin Wattenberg and Fernanda Viegas created to show wind flow, the NOAA Great Lakes Environmental Research Laboratory mapped water flow in the Great Lakes, based on forecasting simulations.
Note: The data presented in this report are preliminary. Ranks and anomalies may change as more complete data are received and processed. Effective November 2011, the GHCN-M version 3.1.0 dataset of monthly mean temperature replaced the GHCN-M version 3 monthly mean temperature dataset. Beginning with the October 2011 Global monthly State of the Climate Report, GHCN-M version 3.1.0 is used for NCDC climate monitoring activities, including calculation of global land surface temperature anomalies and trends.
WeatherSpark is a website that has changed how I look at the weather. Like most other weather sites it provides a local forecast based on a variety of data sources including NOAA (there are international data sources for those outside the US). Unlike some other sites, like Weather Underground or Weather.com, WeatherSpark is built on the idea that the user should control what data is displayed using either real-time data or historical trends.
In order to improve long-term predictions of global climate change, we need more information about the current and changing environment. Unfortunately, in the current era of government budget problems, expensive satellite climate studies are being cut, so it is important to identify the measurements we need the most, choosing among things like air temperature, pressure, humidity, radiance at various wavelengths, radiation transfer to and from the surface, etc.
The placement of each line represents a rainfall measurement, and the length and end placement is based on urban consumption. Lines pulled farther from its source change to black. The data comes from two sources: USGS for water consumption and NOAA/NWS for rainfall data provided.
