Cloud the bottom of the hierarchy. Clouds in the troposphere assume five physical forms based on structure and process of formation. These forms are commonly used for the purpose of satellite analysis. They are given below in approximate ascending order of instability or convective activity. "Non-convective" stratiform clouds appear in "stable" airmass conditions and, in general, have flat sheet-like structures that can form at any altitude in the troposphere. The stratiform group is divided by altitude range into the genera cirrostratus (high-level), altostratus (mid-level), stratus (low-level), and nimbostratus (multi-level). Fog is commonly considered a surface-based cloud layer. The fog may form
Term sheet purchase agreement and related agreements will cover in detail. The advantage of the abbreviated term sheet format is, first, that it expedites the process. Experienced counsel immediately know generally what is meant when the term sheet specifies "one demand registration at the issuer's expense, unlimited piggybacks at the issuer's expense, weighted average antidilution"; it saves time not to have to spell out the long-form edition of those references. Second, since the term sheet does not propose to be an agreement of any sort, it is less likely that a court will find unexpected promissory content; a "letter of intent" can
