Modeling Tip

Defining Custom Sectors in WRPLOT View

A wind rose depicts the wind frequency in specified wind direction sectors and wind speed classes for a given location and time. Over the years, thousands of people in need of wind roses have turned to Lakes Environmental’s freeware application, WRPLOT View. Beginning with WRPLOT View Version 8.0, users now have the ability to define custom wind direction sectors. By changing the sector arcs and starting angles, users can analyze a wide variety of wind statistics.

To customize the wind direction sectors, open your met data file in WRPLOT View and select the Tools | Wind Rose Sectors menu option.

The application defaults to 16 sectors centered on 22.5-degree intervals (e.g., 0°, 22.5°, 45°, etc.). To modify the sector positions, edit the Start Angle field. For example, if I wanted to start the sectors at the North compass point, I could start at 0° and go up by 22.5° increments.

    Default wind sectors

    Custom wind sectors

Users can also define non-uniform arcs.

Delhi Air Quality Remains ‘Severe’, Minister Calls for Emergency Meeting

At 9 AM PM showed Delhi’s Air Quality Index (AQI) at 999 in RK Puram at 999, 436 at Indira Gandhi International Airport (IGI), 999 in Punjabi Bagh at 999 and 662 in Shanti Path area.

British Court Rules Government Failing to Tackle Air Pollution

November 2, 2016 - UK government measures to tackle air pollution still don't comply with European Union legislation to improve air quality and meet nitrogen dioxide limits, Britain's High Court ruled on Wednesday.

Nitrogen oxides reduce air quality and member states have been flouting EU limits on a range of pollutants associated with respiratory and other illnesses and more than 400,000 premature deaths per year, according to European Commission data.

The GHG Manufacturer Performance Report for 2015 Model Year finds automakers went beyond the model year (MY) 2015 standards by an average 7 grams of CO2 per mile, equivalent to 0.9 miles per gallon (mpg), even as the fleet-wide standard became more stringent by 13 grams of CO2 per mile. All large manufacturers have met the standards through MY 2015.

Wave of Environmental Regulation Heading for California Ports

November 1, 2016 - The tightrope that California ports must walk in balancing the commercial needs of their private-sector tenants with the demands of state and local environmental regulators played out last week at events in Oakland and Los Angeles-Long Beach.

On Thursday in Los Angeles, John McLaurin, president of the Pacific Merchant Shipping Association, warned a Propeller Club gathering that the environmental movement in California is moving inexorably from an emphasis on reducing health-risk pollutants, where the ports have achieved great success, to reducing greenhouse gas emissions.
