A large, faintly colored, circular arc formed by light (usually sunlight) falling on cloud or fog. The apparent center of the cloudbow is the antisolar point (the shadow of the observer's head or possibly the shadow of the plane in which the observer is flying). The term rainbow is a general term for this phenomenon, a cloudbow merely being a rainbow formed in the smaller cloud or fog droplets. The broad whitish appearance of the cloudbow and slightly smaller angular radius certainly demonstrate that an explanation that treats light as a series of rays does not work very well for small droplets.

The splitting of rocks as the result of the freezing of the water contained in them. The individual fragment produced by this process is called a congelifract.

A range of values (a1 < a < a2) determined from a sample by definite rules so chosen that, in repeated random samples from the hypothesized population, an arbitrarily fixed proportion (1 − ε) of that range will include the true value α of an estimated parameter. The limits (a1 and a2) are called confidence limits or fiducial limits, the relative frequency (1 − ε) with which these limits include α is called the confidence coefficient, and the complementary probability ε is called the confidence level. As with significance levels, confidence levels are commonly chosen as 0. 05 or 0. 01, the corresponding confidence coefficients being 0. 95 and 0. 99. Confidence intervals should never be interpreted as implying that the parameter itself has a range of values; it has only one value, α. On the other hand, the confidence limits (a1, a2), being derived from a sample, are random variables the values of which on a particular sample either do or do not include the true value α of the parameter. However, in repeated samples, a certain proportion (viz. , 1 − ε) of these intervals will include α, provided that the actual population satisfies the initial hypothesis.

According to the Norwegian cyclone model, the situation where a cold front catches up with a portion of a warm front above the cold frontal surface. This conceptualization of cold type occlusion development is not often observed in nature; however, it is undisputed that in strong cyclones the low center often retreats toward the cold air separating itself from the cold and warm fronts. A trough in sea level pressure is found between the cyclone center and the wave on the front, and this trough is the occluded front. Regardless of the formation processes, characteristics of a cold type occlusion are 1) a warm temperature or thickness ridge along the occluded front; 2) a trough in the sea level pressure field along the occluded front; 3) relatively colder air behind the front; and 4) an increase in lower-tropospheric static stability behind the front.
