  • 7 of 10 | Sierra Nevada Mountain range and midday clouds

    View with alternate video source

    Scene notes:

    Panning digitally upwards, while the mountains display four levels of cloud cover, with two on its peaks or flank. Altocumulus appears to follow the low clouds caught on the peaks, with the same amount of evaporation once over. The fourth layer is the high-altitude Cirrostratus, a layer of thicker Cirrus, not affected by the lower mountains.
    Time-lapse length (30 fps):
    12 seconds and 20 frames.

    Scene notes:

    Cumulus picking up more reddened light due to the angle of the sun. The light is post-sunset. Clouds at low and medium levels move in the same wind overhead and past. A three second interval is used.
    Time-lapse length (30 fps):
    33 seconds and 21 frames.

  • Behind some trees, Lake Tahoe and a pink sunset of Cirrus

    Scene notes:

    Even the snow of the foreground is pink from the ambient light of the clouds. A fiery canvas ablaze with the day’s last minutes, streaks of vibrant crimson and passionate pink ignite the western sky. Below, a tranquil expanse of water mirrors the celestial drama, reflecting hues of rose and lavender. Silhouetted pines stand sentinel along the snowy banks, their dark forms a stark contrast to the luminous horizon. Distant, snow-capped peaks fade into a soft, ethereal blue, a gentle boundary between earth and the incandescent heavens. The snow continues in the distant mountain Mt Tallac (far away and at right).
    Time-lapse length (30 fps):
    27 seconds and 23 frames.

  • Under Mount Whitney and others, clouds pass by in the sky, transforming and casting shadows on peaks

    View with alternate video source

    Scene notes:

    Sharp peaks up close: young granite spires and glacial erosive features are featured in the lower ragged third of the frame, while low clouds transform just overhead left-right. On the sheer stone cliff faces, shadows are clearly moving past. Drops of solid rocks give way to trees where the less steep terrain allows any growth.
    Time-lapse length (30 fps):
    12 seconds and 21 frames.

  • Near but not colorful, formation of upper-level clouds moving overhead

    View with alternate video source

    Scene notes:

    An example of what happens most evenings with clouds beyond the horizon. No light comes through below to illuminate. The thicker the cloud, the less light passes through it. A finely detailed Cirrus formation with interesting feather-like shapes. For periods of under-lighting, see almost any other clip in the Dawn and Dusk.
    Time-lapse length (30 fps):
    38 seconds and 21 frames.

  • Cloud overhead glows bright and then dims under…

    Scene notes:

    … higher clouds at sunset. Post-sunset, underneath the clouds, the light is caught. Moving to the right, a gradual clearing of glowing mid-level clouds give way to Cirrus clouds still bright in the sunset light in the upper-right half of the frame.
    Time-lapse length (30 fps):
    19 seconds and 11 frames.

  • 2 of 10 | Sierra Nevada Mountain range and midday clouds

    View with alternate video source

    Scene notes:

    Towering congestus clouds, benefiting slightly from orographic lift, float from the peaks of the southern Sierra Nevada range. As tall as the mountains they seem to stand on, they transform as they grow and lose energy away from the peaks, evaporating. On these snowy mountains, their shadows travel. Under the blue sky, which is four-fifths of the frame, high Cirrus clouds move the opposing direction.
    Time-lapse length (30 fps):
    12 seconds and 29 frames.

  • Morning virga clouds with cirrus mixed around

    Scene notes:

    High level clouds with some streaking; ice crystals slowly spreading out in lines as the strong jet stream pushes them along rapidly overhead with low transformation.
    Time-lapse length (30 fps):
    21 seconds frames.
