New Features and Revision History

This section should be very instructive even if Version 2017, Build 1.1 is the first version you've used.

Version 2017, Build 1.1, was completed May 15, 2017 and has the following changes relative to Version 2017, Build 1.0 (described below):

(1) Data types were added in the cty.fdt file to enable more versatility with wind speed forecasts for wind turbines (typically between 40 and 80 meters above the surface). The wind behavior can now be made even more site-specific than before (allowing for a range of surface roughness and inversion-proneness) and also can now supply winds at two heights (one half that of the other, customized one). Note that this feature is available only if it was included in the customization.

(2) wret.exe can now handle a change in file names in CumulusMX, where (at elast under Spanish settings) a period now appears after the month abbreviation. WXSIMATE and WXSIM-Lite also had changes allowing for this. In each case the name change is auto-detected, so no user action is required.

ADDITIONAL NOTE: Occasionally users may encounter Permission Denied (VB error number 70) errors, which shut down the program. I declined to attempt anticipating all such errors in my error trapping code, out of concern about interfering with other error trapping routines. The cause is usually very simple: a WXSIM file is being used by another process, which CAN be another program in the suite (i.e. WXSIMATE), if that programs gets stalled somehow or is scheduled to run overlapping with WXSIM. Another cause of the problem could be if the user has opened a file such as latest.csv or latestturbine.csv for viewing in Excel, and left that open. Being alert to these possibilities will likely prevent the error from ever appearing, or at least make it fairly easy to fix if it ever does.

 

Version 2017 (Build 1.0, February 18, 2017) had the following changes relative to Version 2016, Build 1.2 (described below):

(1) Added the ability to customize shadowing by mountains, and effects of sloped terrain in general (on solar radiation)

(2) Fixed a bug which on rare occasions caused the date to revert to the start date during the forecast (I think only one user ever reported this, but I was able to reproduce and fix the problem)

(3) Added an option (under Start/Auto run and Other Settings) to omit humidity (dew point) bias and WXSIM-Lite corrections, which keeping all the temeprature stuff. This was mainly motivated by one user whose station's hygrometer totally failed, but I've seen other questionable humidity data in users' files before, so this may have some wider application.

(4) Created WRETMATE, a companion program (openable either alone or via buttons in wret.exe, autolearn.exe, or wxsimlite.exe) which allows you to easily manage the large number of old forecast (.wxf) files which can acculate over time and potentially make WXSIM-Lite or WRET/Autolearn rather slow in completing their analyses for bias corrections ("learning"). This new program allows you to (reversibly quarantine archived forecasts that are too old or have non-standard names. It also lets you randomly cull the list of forecasts down by a percentage of your choice (i.e. if you were making forecasts every hour, you could trim the analysis set down to, say, an average of 5 per day, for quicker processing).

Version 8.1 (July 3, 2001), had the following changes relative to Version 7.3 (described below):

Version 7.3, finalized April 12, 2001, includes one change from Version 7.2.9, in response to a small change in the format of READY meteogram data: the year is now four digits instead of two. Version 7.3 properly reads the new format as well as the older ones.

Version 7.2.9 (April 3, 2001) included three changes from Version 7.2.8:

Version 7.2.8 (finalized March 17, 2001) corrected a problem which allowed the duration of READY data to interfere with that of FOUS data. Version 7.2.7 (March 17, 2001) allowed for import of new, slightly differently formatted (in the date/time section - already corrected in version 7.2.6 - and now also in the forecast hour line) READY meteogram data, though it can still import the older formats, too. Version 7.2.5 (January 25, 2001) added the option of dots as date separators, as used in some parts of Europe. Also, an oversight, which had allowed the chosen time interval to influence the effect of the (optional) Recent Temperatures/Last 4 Days input, was corrected. Version 7.2.3 (January 11, 2001) corrected a rarely encountered division by zero error that happened when importing READY meteogram data if the V component of wind was exactly 0.00. Version 7.2.2 (January 9, 2001) improved handling of the effect of nearby moderate-sized bodies of water for certain sites. Version 7.2.1 (December 31, 2000) corrected a minor RAOB import bug in Version 7.2 that had caused erroneous 1000 mb heights when that height was below sea level.

Version 7.2, finalized December 27, 2000, contained significant new features and changes:

Version 7.1.3, finalized November 5, 2000, contained the following changes from 7.1:

Version 7.1.2 was finalized on September 16, 2000, enabling use of another format of TTAA data, in which all lines after the first are indented. Also, a bug which caused inaccurate initialization of 1000-500 mb thickness on the interrupt planner (only when FOUS and advection METAR were both imported) was corrected.

Version 7.1.1 was finalized on September 11, 2000, correcting a bug that caused the program to shut down when using the 'Start Fresh' option. The only changes from 7.0 to 7.1 were two bug corrections: a problem with RAOB import when using French Regional Windows settings was corrected, and a text alignment problem when using a certain graphics mode was corrected by expanding the text width options.

Version 7.0 was finalized on August 18, 2000, and included the following improvements over Version 6.4:

Version 6.4 was finalized on February 19, 2000, and included the following improvements over Version 6.0: Version 6.0 included several advancements made since the release of V5.4 about a year ago, as follows:
Between Version 4.0 and 5.4, a MAJOR data collection and program calibration effort was undertaken. This involved many years' (up to 30 in one case) worth of hourly surface data from several stations, correlated with upper air data using a program written especially for this purpose. (The data sources were the National Climatic Data Center's SAMSON CDROM and North American Upper Air Data 1946-1996 CDROM. I wrote the extraction and analysis program).

V5.4 included many improvements made since the release of V4.0 about two years ago, as follows:
