Reports from the National Data Buoy Center's Stations During the Passage of Hurricane Dean

13-23 August 2007

This report provides a summary of some of the wind speed parameters, the sea-level pressure and wave parameter reports from National Data Buoy Center (NDBC) stations in the vicinity of Hurricane Dean's track.

Figure 1: NDBC stations within 300 nm of Dean's track. Note: Stations 42057 and 42058 were not reporting during this period.

Wind Speed: Wind speeds are reported in meters per second to a resolution of 0.1 m/s. For the plot legends:

CWS: The average wind speed over a 10-minute period at the anemometer height. In this report, data are plotted at the time of the end of the valid 10-minute period.

MXGT1: The peak 5-second gust during the past hour at the anemometer height. The time of MXGT1 is reported to the nearest minute, however, in this report data are plotted at the valid time of the hourly report.

MX1GT1: The peak 1-minute wind speed during the past hour at the anemometer height. The time of MX1GT1 is reported to the nearest minute, however, in this report data are plotted at the valid time of the hourly report.

Pressure: Pressure is sampled at a rate of 1.0 Hz and reported to a resolution of 0.1 hectoPascal (hPa). For the plot legends:

BARO1: Sea-level Pressure. The buoy stations average the pressure over 8-minutes.

MN1MSLP1: Lowest sea-level pressure averaged over a one-minute period. Some stations report this value in addition to BARO1.

Wave: The wave sampling rate of all stations in this report is 1.7066 Hz.

WVHGT: The significant wave height that represents the average of the highest one-third of the waves during the wave sampling period.

DOMPD: The Dominant Period that represents the wave period (time between consecutive passes of the wave crests) of the waves with the most energy.

Closest Point of Approach (CPA): Time, bearing (degrees true), and distance (nautical miles) from the station to Hurricane Dean at CPA are computed using the positions from the National Hurricane Center's advisories that have been interpolated to hourly values for positions.
