Final answer:
The correct answer is 'radar summary chart / 35', which provides updated weather radar reports every hour at 35 minutes past the hour, enabling chronological tracking of weather patterns.
Step-by-step explanation:
A radar summary chart is a graphic representation that collates various weather radar reports, also known as Storm Detection (SD) reports. This type of chart gives an overview of weather activity, such as precipitation, and storm locations at a glance.
The chart is updated and published every hour, specifically at 35 minutes past the hour. It's an essential tool for meteorologists and others who need to track weather patterns and make forecasts.
Keeping in mind the key points about the chart's timeliness and utility, it's important to remember that weather data like those shown on a radar summary chart is not random but ordered chronologically.
This enables a clear understanding of weather progressions over time, similar to how a time series graph would illustrate changing temperatures throughout a month, as indicated in the reference provided.
