Time-lapse photography of clouds and other phenomena in the sky

Early morning fog above south parts of Praha. In the beginning of the sequence, at the left part of the view, we can see a typical river valley fog above Vltava River, drifting north, towards the city center. Later on, increased amounts of advection fog at somewhat higher levels, brought by stronger winds from south, hide the view for about one and half hour (skipped in the sequence). In the second part of the sequence, as the fog gradually dissolves, the scenery clears again. See also this Metop image (data source: EUMETSAT and CHMI) where the red dot indicates the location from which the sequence was captured - CHMI Observatory Libuš, Praha, Czech Republic (northward view).

Sunset from Muscat, Oman. Lecturing for EUMETSAT brings me sometimes to countries, which for most of us are rather exotic. In this case to Muscat, at the eastern part of the Arab Peninsula. Given its location at the Tropic of Cancer, the Sun sets here to hazy and dusty atmosphere much steeper than what we are used to from central Europe. The mountain at the left part of the frame is Jebel Shams (3009 m), the highest peak of the Arab Peninsula. Captured from the Sultan Qaboos University (SQU), Muscat, Oman.

Sky above České středohoří I.  Cirrus clouds and weak shallow convection above southwest part of České středohoří (Böhmisches Mittelgebirge). First part of this sequence was captured through IR filter (R72), second part in regular, visible light. The IR filer significantly increases contrast of clouds against blue sky, and also all the vegetaition appears much brighter in IR as compared to normal light (see also this image, comparing the two spectral bands). Left of the image center is Raná hill, in its center (further away) is power plant Počerady. Captured from the top of Oblík hill (509 m a.s.l.), district Louny, Czech Republic, westward view. 

Sky above České středohoří II.  Shallow convection above central parts of České středohoří (Böhmisches Mittelgebirge). Almost in center of the frame is Milešovka (837 m a.s.l.), highest hill of České středohoří. Captured from Holý vrch (458 m a.s.l.) small hill above Sutom, district Litoměřice, Czech Republic, northwest view.

Sky above České středohoří (Böhmisches Mittelgebirge) III.  Smaller, insignificant cumulonimbus cloud, core of which evolved above Czech-German borders, near Klínovec mountain. Elongated anvil of this Cb stretches eastward, carried by upper-level winds, towards the observation location. See also this MODIS-Aqua image, captured at 11:38 UTC (with indication of the place from which the sequence was captured) and this MSG loop (with the Cb and time range of the sequence being indicated by red ellipse). Captured from top of Oblík hill (509 m a.s.l.), district Louny, Czech Republic, westward view. Satelite data source: NASA, EUMETSAT and CHMI.

Storm season begins ... Smaller Cb west of Prague. Captured from roof of the CHMI Observatory Praha Libuš, Czech Republic (westward view). See also the NOAA-19 image taken at the beginning of this sequence, when the 3m antenna dish follows the satellite; red dot indicates the location from which this sequence was taken. Satellite data source: NOAA and CHMI.

Cb clouds above northern parts of Bohemia. Captured from Okrouhlík (Křížkový Újezdec, district Praha-východ, Czech Republic), processed from DNG files. See also the radar animation (data source: CHMI) of this case, with location and time range of this sequence being indicated by a small cross (first episode there, northward view).

Inflow area of a storm.  Two shorter consecutive timelapse series, showing a very active inflow area of a storm. The storm itself exhibited cell splitting during this sequence, see the radar loop (data source: CHMI) for this case, with location and time range of this sequence being indicated by a small cross (second episode there, north-east view). Captured from Radějovice, district Praha-východ, Czech Republic.

Moonrise above Dachstein and Gosausee. Captured on "Blue Moon" evening from shore of the Vorderer Gosausee, Salzburgerland, Austria. 

Hidden Dachstein. Splashing and streaming clouds above Dachstein and Vorderer Gosausee, Salzburgerland, Austria.

Ötztal Alps from Gaislachkogel. Broken cumulus clouds above snow-covered peaks surrounding valley of Vent. Most of these peaks range high above 3000 m, with the highest of these, Wildspitze, the highest mountain in the Ötztal Alps and in Tyrol and the second highest mountain in Austria, reaching 3770 m.

"Waterfall" of clouds above peaks of Gurgler Kamm in the Ötztal Alps. Rotmoosferner glacier rights, and Gaisbergferner glacier left. Captured from Hohe Mut Alm (2653 m), Tyrol, Austria.

Game of light and shadows. Solar rays dancing on remains of morning fog above a small, moss-covered glade in forests southwest of Praha (Brdy Hills, central Bohemia, Czech Republic).
