Description

Hurricane best track database (HURDAT2).

Pacific basin 1949-2018.

Table Schema

Table Schema

Name	Type	Description
seq	DOUBLE	ATCF cyclone number for that year
name	STRING	Hurricane name. e.g. "ALEX"
datetime	STRING	Observation time in UTC. Format is YYYY-MM-DDTHH:MM:SS.
record_id	STRING	Single letter desinating a specific event in a hurricane track. An empty string if no code. C - Closest approach to a coast not followed by a landfall G - Genesis I - An intensity peak in terms of both pressure and wind L - Landfall (center of system crossing a coastline) P - Minimum in central pressure R - Provides additional detail on the intensity of the cyclone when rapid changes are underway S - Change of status of the system T - Provides additional detail on the track (position) of the cyclone W - Maximum sustained wind speed
status	STRING	Status of system: DB - Disturbance (of any intensity) ET - Unknown. The only occurrence is in HARVEY. EX - Extratropical cyclone (of any intensity) HU - Tropical cyclone of hurricane intensity (> 64 knots) LO - A low that is neither a tropical cyclone, a subtropical cyclone, nor an extratropical cyclone (of any intensity) SD - Subtropical cyclone of subtropical depression intensity (< 34 knots) SS - Subtropical cyclone of subtropical storm intensity (> 34 knots) TD - Tropical cyclone of tropical depression intensity (< 34 knots) TS - Tropical cyclone of tropical storm intensity (34-63 knots) WV - Tropical Wave (of any intensity)
max_wind_kts	DOUBLE	Maximum wind speed
min_pressure	DOUBLE	Minimum pressure
numEntries	DOUBLE	Number of points for a particular hurricane
radii_ne_34kt	DOUBLE	34 kt wind radii maximum extent in northeastern quadrant
radii_se_34kt	DOUBLE	34 kt wind radii maximum extent in southeastern quadrant
radii_sw_34kt	DOUBLE	34 kt wind radii maximum extent in southwestern quadrant
radii_nw_34kt	DOUBLE	34 kt wind radii maximum extent in northwestern quadrant
radii_ne_50kt	DOUBLE	50 kt wind radii maximum extent in northeastern quadrant
radii_se_50kt	DOUBLE	50 kt wind radii maximum extent in southeastern quadrant
radii_sw_50kt	DOUBLE	50 kt wind radii maximum extent in southwestern quadrant
radii_nw_50kt	DOUBLE	50 kt wind radii maximum extent in northwestern quadrant
radii_ne_64kt	DOUBLE	64 kt wind radii maximum extent in northeastern quadrant
radii_se_64kt	DOUBLE	64 kt wind radii maximum extent in southeastern quadrant
radii_sw_64kt	DOUBLE	64 kt wind radii maximum extent in southwestern quadrant
radii_nw_64kt	DOUBLE	64 kt wind radii maximum extent in northwestern quadrant
basin	STRING	Ocean basin. Always one of: CP - North Central Pacific EP - Northeast Pacific
id	STRING	Code for a particular hurricane. Basic code followed by a 2 digit cyclone number followed by a 4-digit year. e.g. "CP011993"
year	DOUBLE	Year in which the hurricane occurred

Visualize as a FeatureView

A FeatureView is a view-only, accelerated representation of a FeatureCollection. For more details, visit the FeatureView documentation.

Code Editor (JavaScript)

var fvLayer = ui.Map.FeatureViewLayer('NOAA/NHC/HURDAT2/pacific_FeatureView');

var visParams = {
  isVisible: false,
  pointSize: 20,
  rules: [
    {
