The word rate is used in two ways within the structure. First, rate is a paygrade. Enlisted navy personnel do not have rank: only naval officers do. Second, rate is an abbreviation that contains both the rating and the paygrade abbreviations.he first steamship, mine, radar, torpedo, aircraft carrier, and many other âfirstsâ all established a new era in the Navy, and each directly impacted the enlisted occupation structure. During World War II, the Navy also briefly maintained a rating of Specialist, similar to the rank in the United States Army.
In mathematics and statistics, a stationary process (or strict(ly) stationary process or strong(ly) stationary process) is a stochastic process whose joint probability distribution does not change when shifted in time.
A stationary front is represented by alternating blue and red lines with blue triangles pointing towards the warmer air and red semicircles pointing towards the colder air. A noticeable temperature change and/or shift in wind direction is commonly observed when crossing from one side of a stationary front to the other. Image by: WXP Purdue. In the map above, temperatures south of the stationary front were in the 50's and 60's with winds generally from the southeast. However, north of the stationary front, temperatures were in the 40's while the winds had shifted around to the northeast.
