Otherwise, individual frames can be loaded one at a time using the forecast hour selection menu, or keyboard shortcuts ← and →. Note: If preloading is disabled, animations will be disabled when data loads, the Play button will change to orange and the page will wait for the user to start an animation by pressing Play to manually request all images. On slow, unstable connections or when data usage is limited it may be preferred that preloading is disabled leaving only the specified forecast hour to be displayed. Most-Unstable where the temperature and dewpoint used come from a data level in the lowest 300mb that results in the highest Theta-E (θ e), subsequently producing the greatest amount of instability given the conditions.Įffective-Inflow where the parcel assumes the mean temperature and dewpoint of the 'Effective Inflow Layer' (the lowest contiguous layer of data levels that result in a conditionally unstable parcel lifted from each respective level).īy default when any product is chosen all images are preloaded, meaning they are downloaded to your browser to enable the ability to animate through the entire forecast. Mean-Layer where the parcel assumes an average or mean temperature and dewpoint from the lowest 100mb AGL (colloquially referred to as a 'mixed' layer parcel). Surface-Based where the parcel assumes a temperature and dewpoint taken directly from the surface data values. In brief terms, the four parcel methods we account for can be interpreted in the following manner Different calculations will often result in distinct differences in the amount of positive or negative buoyancy throughout the depth of the profile. The thermodynamic profiles included in forecast soundings are generated using specific methods for calculating the thermodynamic properties of the theoretical parcel that is lifted from the surface. Use this setting to specify a default parcel type for forecast soundings. Updated version of legacy forecast sounding viewerįorecast Sounding - Parcel Type: (?)

This eliminates subjective text only sector selection to avoid confusion.

Sector selection is exclusively performed with a sector map, now always available from the animator.

Forecast soundings are generated with a 1 second long click on applicable data.

Data-Friendly settings to disable preloaded images and auto-updates available in 'Settings' menu access from gear icon on the animator.

User-Defined preferred Sector and Product available in 'Settings' menu access from gear icon on the animator.

Forecast sounding settings are accessed from the 'Settings' gear icon on the animator.

Model Comparisons are accessed from the 'Comparison Products' icon on the animator.

Many of the supplementary page and product features have been moved to 'Feature Toggles', Icons in the upper-left of the animator.

This new page uses our in-house HTML5 animator.

With this new page, we attempted to either add new features or remedy short-comings of its predecessor. A mobile version of this page is still in development. Because of this we recommend viewing this page at a 16:9 or 16:10 aspect ratio at a resolution of 1920x1080 or greater.

The overwhelming majority of the imagery on this page is rendered at a resolution of 800圆00 pixels, however we are engaging in discussions of increasing the resolution of our forecast imagery. If you are curious about feature development and/or want to float an idea passed our development staff, we are certainly open to suggestions from our users. DISCLAIMER: This page is undergoing active development.
