[[കാറ്റ്|കാറ്റിന്റെ]] വേഗം അളക്കുന്ന ഒരളവാണ് ബ്യൂഫോർട്ട് സ്കെയിൽ (The Beaufort Scale). പ്രധാനമായും [[സമുദ്രം|സമുദ്രത്തിലെ]] കാറ്റിന്റെ വേഗമറിയുന്നതിനും അളക്കുന്നതിനുമാണ് ഇത് ഉപയോഗിക്കുന്നത്.
 
== ചരിത്രം ==
ബ്രിട്ടീഷ് നേവൽ ഓഫീസർ റിയർ-അഡ്മിറൽ [[സർ ഫ്രാൻസിസ് ബ്യൂഫോർട്ട്]] എ.ഡി.1806 ൽ ആണ് ഈ സ്കെയിൽ കണ്ടു പിടിച്ചത്. അതുവരെ നാവിക ഉദ്യോഗസ്ഥന്മാർക്ക് കാറ്റിന്റെ വേഗതയോ ശക്തിയോ അളക്കുന്നതിനും മറ്റും കൃത്യമായ മാനദണ്ഡങ്ങൾ ഉണ്ടായിരുന്നില്ല. അതിനൊരു പരിഹാരമായാണ് ബ്യൂഫോർട്ട് സ്കെയിൽ കണ്ടുപിടിക്കപ്പെട്ടത്.

|rowspan=4| [[Storm]],<ref name="forcenamenote">The names "storm" and "hurricane" on the Beaufort scale refer only to wind strength, and do not necessarily mean that other severe weather (for instance, a [[thunderstorm]] or [[tropical cyclone]]) is present. To avoid confusion, strong wind warnings will often speak of e.g. "hurricane-force winds".</ref><br />[[Whole gale]] || 89–102 km/h ||rowspan=2| 9–12.5 m ||rowspan=4| Very high waves with overhanging crests. Large patches of foam from wave crests give the sea a white appearance. Considerable tumbling of waves with heavy impact. Large amounts of airborne spray reduce visibility. ||rowspan=4| Trees are broken off or uprooted, saplings bent and deformed. Poorly attached asphalt shingles and shingles in poor condition peel off roofs. ||rowspan=4| [[Imageപ്രമാണം:beaufort scale 10.jpg|120px]]
