Anvil cloud--The cirriform
layer that spreads out horizontally from the top of the storm.
1986: Ice particles observed in a cirriform
cloud at -83[degrees]C and implications for polar stratospheric clouds.
This species has a solid-reddish body, but chaetiger four is pure white; the antennae are banded with the median being two-three times longer than peristomial width, but peristomial cirri are cirriform
The last known picture taken shows signs of undulation motions or wave action at the cloud top, with a higher band of cirriform
cloud layer further south along the track.
The air along and just above the frontal surface is typically filled with broken to overcast stratocumulus, altocumulus, and cirriform
1A, B) slender and cirriform
or short and papilliform (might be retractile); remaining ones more stout and tapering to a short tip, somewhat longer than postchaetal lobe, bearing two dark glandular ridges but lacking fimbriation (Fig.
